Have you considered new alloy heads?

I'd give COME a call and ask them. The original VN-VSIII heads are pretty good standard, they handled the factory 350ci HSV engines OK.

If we all had the same (good) taste, who would buy all the Fords?

The factory iron heads are pretty damn good for 90% of engines but with a blower im not sure the exhausts in ANY of the factory heads will let it breathe well enough to make good use of the pump.
