This is actually a very good question. I myself would like to know the answer and so, I'm chiming in here so that I can get email updates when someone posts.

But also, I have this question. Does anyone have any idea how much better than stock headers even flow?

The reason that I ask is that, on my old 71 C20 with the 350, I had the ram's horn center dump manifolds. When I switched to headers, I never really could see any real improvements in performance. But, with all of the disadvantages of headers (such as leaking and constantly cooking the starter) I couldn't see where they were ever worth it. So, I was wondering if it would be the same on the Big Block engines.

(yeah, I finally went back to the original ram's horn manifolds and never looked back.)
