Quote: I agree with patrick on the headers only because Comp Cams Program showed around the same gains going to small tube headers vs using HP log manifolds.
I wonder if the same would hold true with HP manifolds that have been cleaned up internally and port matched?
I would imagine if you had them extruded out a bit I would think there would be some marginal difference. I mean after there is guys in the FAST class that has some good tricks up their sleeve.
