I'm trying to install headers on a factory 4.3 in a 1986 el camino. The engine has plenty of life left and i know getting rid of the awful exhaust design these had originally will boost power by a lot. I looked around in the forums and no one has found any headers that drop right in. If anyone can help please!

Why not buy a set of cheap 4.3 S10 headers and send it? I imagine it’s a similar case as the 73-77 A body, in theory at least.

I thought 4.3l engines came with factory headers instead of cast iron manifolds.

I actually don't know if they are cast or not. I assume they are. Ill check now. But my main problem is how they flow. I just want a design with collectors basically
