Has anyone installed headers on their medium duty?
 

I need to install exhaust on my truck.

I have a nasty exhaust leak from a broken flange on one of the exhaust manifolds.
I have not had much luck finding a replacement manifold locally and decided installing headers is an easy way to go.

When I look for headers at some of the common websites, I can find nothing that includes any of the medium duty trucks. Am I looking in the wrong places?
I have searched many of the manufacturers as well, but to no avail. C30 is as large as they go.

I have read on this forum that pickup headers “should” fit, but I would prefer to know before ordering if possible. I have a bad habit of - if something I bought does not work or fit, toss it aside and never return it. Wife calls it "lazy". I dunno what she is talking about.

Many years ago (35 years ago??), I had a 72 C60 with a small block. It threw a rod and I replaced with a 454.
At that time, I had no problems finding a set of headers for that truck but I don’t remember where I ordered them from. But it was not challenging at the time.

Today, I have a 76 C60 with a 366 (among others), but can find nothing for any medium duty.

Does anyone know of anyplace to find correct headers?

The factory installed exhaust on the later model square medium duties was a set of headers. My 89 has them, looks odd to see a set of headers with emissions tubing :lol: That's actually one of my next projects, all the emissions garbage is gone from mine, so I want to remove the headers and take off the tubing and plug the holes.

I've seen them for sale, may take some hunting but they're out there.

I have 2 sets of factory manifolds that came off of 427s. I attempted to install a set of long tubes on my truck with no luck and ended up going with a set of block huggers.

Here's the factory ones. VERY similar to the block huggers above, do you remember what huggers you went with Pvmt-Pndr? I'm sure they would be much easier found than the factory type.

I can't locate the exact ones I went with but they're ss and didn't break the bank. I did have to clearance one of the tubes on the passageners side slightly, it hit the frame rail. I built my own exhaust from scratch using a diy kit I bought so I was open to using any headers that actually fit because I could make anything work from that point on.
