Another head choice question...
Torn between AFR 190's, Edelbrock, or GM Fastburn. TBI 350 with LPE 224/234 471/494 cam. The AFRs and GM ones flow more than the Edelbrock, but Edelbrock has gotten over 400hp out of them. The AFRs always get nice print and seem well built, and of course the GMs have their "fastburn tech". Arghh. Since the Edelbrock ones have smaller(170 to 190)runners and flow less, but still enough for 400+hp, would this mean higher charge velocity and thus higher vacuum?

According to www.paceparts.com, where they sell GM performance parts, the FastBurn heads are capable of making 430hp with the combo of Hot Cam and 1.6 rockers.
