What's your opinion on 'stroke ability' of heads that flow:

Int
.400 260CFM
.450 283CFM
.550 319CFM
.650 348CFM
.700 353CFM

Exh
.400 215
.450 228
.550 240
.650 249
.700 252

Depends on how much cross section you need and how much cross section it took to get those numbers, as well as the length of the runner.
