Cylinder head flow vs port size...
Lets say that you have 2 cylinder heads...
Head 1)
200CC runner
flows average 225cfm across the board
Head 2)
230cc runner
flows average 258cfm across the board
Head 3)
250cc runner
flows average 280cfm across the board
Which head would you run? What would be the differences in these heads since they have very similar CFM to CC flow #s?

Throw in on that the port length so you can have an idea of the average cross section of the heads..... let alone lets make sure we know the cubes and the RPM range.
Basically there are a lot of things I would look at over this than just average CFM and port volume. IMHO average cfm means crap anyways.
