Thanks for the reply and the info. They both look like good heads. I spoke with Best Machine about hemi heads and they suggested the Victor because of price and they come with bigger valves, but does bigger valves guarantee more flow in a hemi head? The stage V has a 168cc chamber and the Victor has 170cc chambers. Looks like the stage v head cnc'd flows 407cfm@.700 and the Victor flows 450cfm BM tells me. Its really hard to find much tech like flow numbers and such about the Hemi engine. Surprised there is not more info out there. Must be top secrete.
