Does anyone have any experience with their headers for a 78-79 Bronco 351M?

I've got their cheap crappy headers on my 302 and they work fine. Nothing wrong with them in the many years I've had them that I can bitch about.

Finally a response. LOL

thanks! I can't decide on Hooker or Flowtech or some short's ( which actually cost more)

did you notice any performance gains from them, or just some additional throaty sound?

I have a header tread I posted about fit, it seems headman is hit or miss, but mostly miss. If you are going chassis exit i'd suggest fenderwell based on what I was told. Chassis exit I have no clue. I'd love full length headers if I could get some that would fit.

Can you explain the difference and why I would want one over the other when it comes to chassis/fenderwell exit?
Whats the reason for the difference?

I havent heard much about Headman that makes me wanna buy, so I ws looking at Hooker.
I would look at sanderson, but I cant tell if they are ceramic coated for the price they are asking?

I've got Flowtechs in my `78 and Hedmans in my `79. Both installed by previous owners. The Flowtechs have quite a few dings in them to clearance them from things, where the Hedmans seem to fit fairly well. but I think the Hedmans have a crack where all 4 pipes meet in the collector.

For sound, the Flowtech's have that typical cowboy truck sound. Very unrefined, raspy and quite obnoxious. Almost an open header type sound but not as loud. The Hedmans sound a bit smoother and deeper. More growl than the snarlier Flowtechs. Both of them are running thru bullet style, straight thru mufflers so the mufflers are not the difference in sound.

Another thing to mention is that the `78 with Flowtechs has the exhaust routed to the passenger side, around the T-case before going dual out the back. The `79 with Hedmans has pipes going under the crossmember and straight out the back.

Were they direct bolt on's or did they require welding?

So, overall you would say Hedmans?
Is it better to run the pipe around the t case, or under? Seems like under would cause clearance issues while off road beatings take place

Yeah when the engine was already at 4000 rpm's it sure felt like it had a lot more power. They sounded like any other unequal length header too.

The way i ran my pipe is through the tranny crossmember. that way everything is tucked up under there and wont be in the way. By the way my hedmans were a direct bolt on. they fit the first time with no mods

Sounds like the way I am leaning.

I am looking for the most simplictic install, small gain in power through the mid range and of course the added sound to pipe through the 2 chamber Flowmasters. I ordered a holly 500 & drop in AirAid filter ( I used to work there, got it for free) to compliment the intake side as well. Should wake this 351 up a little.

Thanks for the info:thumbup

I even considered gettin my headmans jet-hot coated. That would look awsome through the fenderwell!:rockon

Nickel coated I believe. You want to look at the headers for Cleveland. Same ones for Bronco.

I'm not sure about the price difference as I know flowtechs are about as cheap as you can get, but yeah the hedmans are a much better fit and sound. And yes, redoing the exhaust is high on my list of priorities as the exhaust is currently the lowest point of the truck, and if I don't reroute it, nature will :toothless
