No. The GT40P's do seem like it, but there is still an angle to the plugs. And you are corect they are straighter in the head. I've liked their performance, I plan on upsizing the valves in a while. Hope to stuff 1.90 - 1.60 in them. But they work great on my 363

I played it safe from the start and got those fiberglass boot covers. I thought that wit hthe amount of money spent in exhaust work, $8 per cover was a good idea.

Side Note:
The 9mm Ford Racing wires seem pretty well built and made to handle lots of heat and stress. I love mine.

Im runnin 4 MSD 90 degree custom wires and 4 accells for a 81 Bronco. I havent built up the last 4 accells cuz I havent found looms nor installed any
my wires look like a tangled mess!! I put header wrap around the tube that practially touches the boot, so far its lasted the longest with that and the dent in it.

So you have the P's as well? on that 320+HP 302? LOL
you really need to get it dyno'ed, LOL. I was rating my truck in the 340's untill I saw the real numbers from the dyno. There is a big difference between preception and fact.

What headers did you use? the MAC set for both sides? If you ever need a passanger side replacement let me know. The MAC 302 header didn't fit on the 351 block.

hmm that doesnt sound good!! What you running for parts??? I didnt exactly stick a stock iron intake and 2 brl carb on there. Im gettin it dynoed as soon as I get it running the way I want it(like better then 4MPGs) Stupid centrificul probillet distributor is a bitch to figure out what springs to run.

Im running Macs both sides. Got em from Central Coast Mustangs, the guy didnt tell me they were direct replacement, just that they would fit the P heads.


I think im gonna fill out my Superford with exactly what I got... then Ill get hood pins with some locks on em!!

Check out my engine on my superford site. not sure what the chassie dyno gave me but i didn't even come close to 200.
BUT, don't mock me or doubt the truck:

story time, LOL:

I once had a friend "test drive" LOL a 95 lightning. Well then I showed up at the light, LOL. the salesguy was clueless. We each aniled it for almost 1/4 mile, or at least untill we were aproaching 80MPH. The 95 lightning was only avout 2 truck lengths ahead of me.

MY TRUCK:
363
B&M drag AOD with a 2.40 first gear
3.55 diff ratio
29" tires

95 LIGHTNING:
351
AODE 2.70 first gear
4.11 diff ratio
30" tires

So the lightning drivtrain should have given him a clear head start. But my engine was compensating for my wimmpy gear ratios.
I'll be swaping to 4.56 / 33" tires this year
And a AODE will be comming in the budget some day.
I'll also be swappign to a TrickFlow 351 intake in the next few months.

SO the Dyno says I suck, But the street says different. This whole real chassie dyno thing makes me wonder what the factory rates engines at.

What was the part number on those gaskets? I have been looking for them but found nothing for the FSB or F-150.

I bet they are rusted already - mine only stayed black for a couple days..

I've tried EVERYTHING - Header paint, POR-20 Paint, and MagnetPaint!. Nothing sticks...

They all burn right off!

hey was doin some searching and found this thread. just like to say great right up 4xPepe`and theres some good gouge on this thread.

i just found a crack in my passenger side exhaust manifold and went to get some jb weld to patch it up and saw that the crack goes all the way around the manifold so it looks like header time. i've been checking out the summit headers just have to come up with the $$$$.

hey 4xPepe` i was wondering how your headers were holding up also???

hey 81Bronk36 does that header wrap keep that area cool??

If you don't have one of those Jet Hot type places in your area there is probably something equivalent. Out here in Utah there is a place called HPC Coating that does the same stuff. When I get some headers I'm taking them straight to HPC.

My friend coated his header and tail pipe on his quad and you can literaly touch the pipe after one to two minutes of sitting after a long ride. Its amazing how cool that coating keeps things.

Also, from what I understand you can coat just about anything with that stuff. I'm also thinking about doing my intake manifold. Sorry plug, but I don't know prices off the top of my head, I know its not pocket change though, but its also not going to break you.

...thoughts arrive like butterflys...

I replied to plugs PM, but for eveyone else... the headers have been holding up great.
They aren't the purtiest things around, but I've got no complaints.
Here's a little shot of drivers side on the new engine... (10 months later)

YOu can see it's starting to look a little rusty, but there's no roblem structurally. They actually look less rusty in person.
Also... changing plugs is a bitch, but not as bad as I originally anticipated.
Cost was under $200 and I had mine overnight.

Thanks D-diesel.
