Missed on this combo?
Took the heads to my machinist/dyno guy, since he's never seen the inside before. Basically he agreed that the SS was murdered beyond REASONABLE repair. We put my cam on his Cam Doctor machine and it checked out dead nuts on the money. He doesn't believe there's much reversion. We did 13 pulls and the intake runners are pretty clean.
Showed him the flow numbers and said throw that away. Yea, they look lousy low and mid lift, but don't live or die on numbers.
So... what he hated that CAN be fixed is how they over-cut the back and sides of the port. Light bulb shaped. My best option is to ditch the heads and buy a pair from Rod Bloomer.
My other option is to epoxy the back, sides and part of the floor to give the air a straight shot into the cylinder. He felt there has to be huge turbulence the way they are now.
Showed me some AFR, Dart, and TrickFlow heads. No lightbulb shaped ports in those
He used modeling clay to give me a sort of "template" as to how to shape them, and gave me the part number for the epoxy they use.
I think I posted 4 pics as they are and 3 of how he wants me to change them. keep in mind, the 3 pics are done with clay and rough but I get the idea.
Also said keep the cam. It is ground correctly and SHOULD make more power. Just changing cams "will not fix this".
so.....at this point, I'm going to goop 'em all up, get them even and smoothed and give it a shot. If that doesn't help, i guess I'm selling some guns and buying a pair of BPE's.
