Exhaust header question
Hello everyone

I have a slight dilema. I just bought a new Hot Rod and I have been trying to figure out what headers I have as they are starting to wear out.

The body is a '49 ford club coupe. The front clip I believe to be from a Camaro. The engine is a from a '74 C-20 454 with the TH400 transmission and a 9" rear end with 4.11's :drool:

The headers that are on there now are a full length header. Where the headers are bolted to the engine each tube is separately bolted (there is no full flange across)
So with all that said. . . the engine compartment on the drivers side is quite full and there is not a lot of room. With so many variations on how the pipes are bent, I don't really want to have to order 2-3 different headers just to find the ones that fit right.
So my question is; is there any way to know or tell what I have already for headers? a stamped code or a brand name?


Should i just bring them somewhere and say I need a set of these. . . LOL

Any help would be greatly appreciated

I have other questions about the car but one thing at a time :)

Sometimes people will cut the flanges to seperate the tubes. If you could post a picture, it may help. If you have a rod shop close, you might take it there and see what they can tell you. Other than looking through books and online for the headers you have, it may be tough to tell you what you need.

Ok Thanks S10racer.

That is weird about people cutting the flanges to make the tubes separate. What would be the purpose of doing that? I just figured it was a low end header from a few(10+)years back.

It's as I figured. I will have to take pictures and try my hardest to match up what I have. There is an exhaust shop that works on a lot of the Hot Rods in my area that might be able to help me out. I guess I will have to see. Maybe I can study them over the winter and try to match them up to something on the summit or jegs web site.

They cut the flange to help with sealing. This is usually only done on the narrow 1/4" thick flanges. The thicker 3/8" flanges are strong enough to stay fairly straight and flat so cutting them are not needed.
Some claim that cutting them also helps keep the header bolts tight but I have no proof of that.

Having a Camaro front Subframe, Camaro Headers may fit.

Narrow it down more on left side of Pg.:
1974 CHEVROLET 7.4L/454 Chevy big block Mark IV Headers - Full-length Header Style - Steel Header Material - Painted Header Finish - No Tuned -

I have been on the summit website looking at all the different configurations. That is what got me concerned that I will pick a set of headers that will not be shaped just right. Once I do find a set you can count on me keeping a record on exactly what it was LOL.

I have a set like your talking about, big tubes long collectors, chassis huggers for ground clearance. they're for 70's Corvette, could be Hooker

Thanks for the input Vinniekq2 and Cridder . I will look into that and see if I can find a match.
