What i don't understand is why SB guys think that they have to have heads that flow over 300cfm to get any power. The BB guys heads flow the same, if not worse....Whats the deal?

So lets say 300 at 600 with over 200 at 300 lift. that would be maybe 2hp per ci..now a big block will get alittle more out of that...but theres over 100ci there. Im just rambaling now....
