Well I think Murphy's law is coming into play here and I think my 460 plans are out of the question for now. My wife's Yorkie is starting to have the same stuff my German Shepherd is going through though hers isn't nearly at the point his was when I took him in. If my Husky gets whatever the hell this is I think I'm gonna shoot myself.
On top of that, I dropped my kids off at school this morning and the battery light in my wife's Honda Pilot came on. Turns out the alternator decided to shit the bed 2 minutes after I started the car. I had it tested at a place that rebuilds starters and alternators and the guy ran the alternator for like 5 seconds and then shut it down as it was whining really bad. He mentioned a couple of things it could be, but that they'd have to open it up to give me a quote on how much it'd cost to rebuild. It'd take a few days at least before I could get it back and that timeline wouldn't fly right now. I went over to Napa which is across the street and got a remanned alternator with a lifetime warranty for... $200. I've really come to appreciate the cost of parts on my old truck, a remanned alternator for it is $50.
Anyway, yeah, vets bills, car parts, Bronco being a turd right now, and then I'm the only one in the house who can keep their emotions in check. lol Oh well, one day at a time.

|Doosenberry||Vet left me a voicemail while I'm here at work and said he's doing better. No more blood, vomit, or rocket propelled Yoohoo out his behind currently. They gave him an anti-nausea shot and that's been helping. They still plan on keeping him over the weekend, but things are looking better. I'm pretty sure he's not going to die, because we haven't gone camping yet in the Bronco and I promised him that.|

Sorry about the dog Doosenberry. Thoughts and prayers heading his way.

I really dislike talking to that block guy. He's really vague and dismissive. I was barely able to get out of him that the block was good. You'd think that'd be a simple yes or no. And then he gave me an "It might need boring". lol Whatever.
Once I found that the block was good I decided to haul everything else into the shop and go from there. Thankfully the owner was there when I went back and I was able to talk with him. He's pretty much the salesman and is a lot more palatable as far as conversation goes. I got up to speed with him as far as what I was doing, making one good engine out of the parts I have from two.
Coincidentally, @cobrajoe , the owner wanted to buy the second crank that I had, the externally balanced one from the short block I dropped off. I jokingly remarked "Oh, is that why the other one was the better of the two for me?" He didn't know he needed one until today though. Apparently another customer has a crank that will need to be turned something like .030-.040 and he'd feel more comfortable buying that crank from me which apparently needs a lot less. So I'll be getting a whopping $50 from it. I probably could have asked for $75 or something as he kinda left the door open on it, but I just took the $50 when he asked if that was alright. That basically pays to have my other crank machined.
I pulled my truck around to their roll-up door and showed him the rest of my goods. Very surprisingly, to me anyway, he said that the head that took the beating from rod #8 would be savable. I questioned that when he said that and he said "oh yeah" like the kool-aid man "as long as it's not cracked it should be alright". Apparently he's seen some shit in his day. That's super good news. However, factory heads don't have the same demand as factory cranks and he didn't want to keep the other set if he's able to save my head. That's too bad, because I don't want/need them and they'll most likely go to the scrap yard with the rest of the unneeded parts I end up with.
I took out the pistons and rods out of the bad block hoping to see if I could reuse them, but it doesn't look like that'll happen. Out of the first 3 I removed 2 of them had busted skirts and the rest were suspect. Oh well. So I'm going to need a new set of pistons, new cam, and a double roller timing chain as I don't want to reuse the gear drive. New bearings all the way around and gaskets and... that might be it other than all the machining. I'm not sure what else.
And then there's some really shitty news for today unrelated to the engine. My dog has been throwing up all morning and the last couple of times I let him out (the last hour or so) he's been shooting blood out his rear end. I really hope it's not Parvo. He's 4 1/2 and within the first couple of months I had him as a young puppy he got Parvo and pulled through. It'd be like the universe has it out for him if he got it a second time. Yes, he gets his shots, which is what blows my mind right now. I'm taking him in as soon as the vet can get him in which is in about an hour. So despite getting some good news on the engine stuff I'm pretty bummed out right now on the whole.

As far as forged and cast I have no idea. The crank that was out of the one I blew up was not the original crank. Before I had the engine rebuilt it had spun some bearings and basically ate a couple of the crank journals on the OE crank. The machine shop owner said it wasn't a big deal and said he could get another one from a Ford friend of his as, at least at the time 15 years ago or so, their specialty was Chevies and that's most of what they had lying around as cores. So, maybe he sourced a forged crank? I doubt it, but who knows. I could always ask the next time I go in and see what exactly what was better about it. I didn't bring the crank home as I wasn't prepared to put it in my wife's car.
The one thing I do like about this particular shop is that these guys have been doing this for as long as I can remember. If I were to guess I'd say they're mostly in their 60's and 70's except for the owner as I think it was his dad's and it got passed down or sold to him. I had that 460 built in '03 or '04 (I can never remember exactly) and minus the head guy, they're all the same guys doing the same thing and they drive the same vehicles which they're probably easy to maintain when you work in a machine shop. The one guy who does all the hot tanking and stripping drives an 80's K5 Blazer and the thing still looks brand new and looks the way it was 15 years ago.
I'm pretty sure it was the owner who was the head guy back when I had my engine built, because I hung around for 10 minutes or so one day after talking with him and watched him do part of a valve job on some heads. He's probably the one who did the port job on my heads as well.

Maybe one of your cranks was forged and the one he said you could take with you was cast?
Machine shops are usually always looking for blocks, cranks and heads; especially on the hard to find and hi-po stuff. That way if you came in with your 460 and he told you the crank was bad, he could sell you one. Don't expect them to give you a lot of money for it though...
Years ago, I had a set of DOAE 1970 Cleveland 4 bbl. heads I had dropped off to have the exhaust port milled off and lowered and the rocker pedestals milled off. Even back then, they were tough heads to come by. Well, the "head" ( yeah, every machine shop is the same way, block guy, crank guy, head guy etc..) guy screwed up the heads, the Cleveland has canted valves and he milled them off parallel with the head, making them basically expensive paper weights. When I asked him what the hell am I supposed to do now?; he said no problem and he walked into the back with me and said I'll just give you these. He had a set of stripped DOAE heads already cut with bronze guides, bagged, sitting on the floor.
So, if you don't use your stuff, you might be helping another 460 guy out down the road.

It's been a couple of weeks and I decided to stop by the machine shop when I was in the area. It wasn't the best time though as we're approaching a holiday weekend and half the shops employees were gone early.
Apparently each guy in the shop only does one thing (heads, block, crank, etc) and the guy I spoke with was the heads guy. He wasn't familiar with where everything else was placed inside the shop as each guy stores their stuff in particular spots I guess. I didn't drop off any heads, so he was kinda useless. lol The guy who does the cranks was there though and he found the crank off the short block I dropped off, so obviously it's been disassembled. I had to explain to him what I had dropped off and why as I had two cranks there already and that was all he could find. He said it'd be best to stop by on Tuesday and speak with the guy who does the blocks as that's my main concern at the moment. I won't likely be moving forward with things if I don't have a good block to work with. The guy I dropped everything off with in the beginning, who wasn't really pickin' up what I was puttin' down, is the block guy apparently. Yay.
What this guy was able to tell me was that both cranks were good, but the first one I dropped off (from the 460 I blew up) was the better of the two and that I could take the other one with me. I thought that was hilarious, that I could grenade an engine and still have the crank in it better than the one from an engine that wasn't exploded. How much better was it? No idea.
The guy also asked if I was selling them the parts I had dropped off, which I didn't know was an option. That was before I had to explain things to him and what exactly I had asked to be done. I guess if the block is bad I could always sell them the other parts. I'll investigate further sometime next week. I'm in no hurry.

Still haven't heard back from the machine shop. Maybe they forgot about me! lol
I'll have to call them sometime or swing by and see what's up. I'm in no big hurry right now on this project, so I kinda don't care as long as my stuff doesn't get "lost" somehow.
I went out and looked at the heads today before leaving to work and sure enough the heads off the 460 I blew up are ported a bit. They removed the ol' hump on the exhaust side. That is bad and good news. Bad, because now I don't have a bad head to practice on. Good, because now I have something I can literally look at while I do it and copy. I'm still in no hurry to get it done, but at least I know how to tackle this project once I get to it.
Head off the "new" 460. It was really hard to get pics inside the ports with how bright the sun was and the amount of shadow that was cast over the ports when I'd get into position. At least in this very first shot you can get a pretty good glimpse of it. The other three pics I had to shove my camera up really close and force it to take a flash pic.
Head off the blown 460. It's hard to tell, but that entire hump just below where the valve passes through is completely gone. There's like a divot where it used to be in one of these pics though, which I'm not sure if that's ideal or if it should be smoother and more evenly rounded than it is. Maybe the guy porting it got a little careless and made a whoops on that port. Either way, these heads were capable of getting my mild build up to 427hp.

Good thing cast iron is self-lubricating!
A rotary burr is not much different than an endmill, which I have experience with.
HSS works, but dulls quickly. A carbide bit will last longer, especially if its coated with Titanium Nitride or Aluminum somethingorother. Cobalt bits are the best for durability, but they are $$$. Expect to drop a Ulysses S Grant on a single GOOD rotary burr.

....But isn't that ALWAYS a good thing?

Not really that bad of a job, just extremely labor intense. All you want to do is grind the bumps down smooth with the rest of the runner. Then just clean everything up by removing the burs. After that, just smooth everything out all the way through and that should increase flow. Remember, you don't want to enlarge the area, just remove anything that will cause turbulence. Just be aware that the area next to the water jacket is thin, but if you do the job right and just blend that area, you will be fine. You could (should) port match the intake ports with the gaskets while you are in there.
There are many articles and threads about this as it is a very common upgrade. Because it is so labor intense, a/k/a expensive, everyone does it themselves, so you will have no shortage of info on this mod. Here is a quick link with pics that may point you in the right direction.
P.S. be prepared to have an ample supply of cutters on hand. IMO, the only type cutters that remove metal and last, are tungsten carbide. Remember, for cast iron heads, you need a fine-tooth cutter as it removes metal faster and will give you a smoother finish.

|Doosenberry||If my old heads aren't ported I'd consider practicing on a bad head. I've never attempted anything like that, so I'm not sure I want to risk going through a water jacket on something I plan on using. I'll have to take a closer look at them sometime.|
