I don't agree, I looked at this before the overall head length is quite a bit different (about 1/2"). If you're going to cut them up that much, might as well make a log manifold and be done with it.

Mike you were able to bow it that far in the past? Which Chevy header fits a mopar body/torsion bar that you were able to do that with?

Not sure if want to stress them that much especially on a turbo deal that's prone to crack anyway.
