Smallblock Heads Help

I agree with 1wild&crazyguy. If the flow numbers are better than what you have and the same chamber size I'd slap them on more HP and torque though out the RPM range without given up much if any bottom end. I think too many people listen to tech that trickles down from Pro Stock and Nacar level of racing and think it pertains to our sub 500hp engine if he was gonna use 300+ cfm race heads on a fairly stock build than I'd think you would be right in saying to much head. One more thing bigger better flowing heads with a smaller cam gonna make more HP and more streetable within reason than smaller less flowing heads and a big cam combo but if you got two similar flowing heads go with the smaller ports.
