Head flow velosity?

Anyone know which heads have the better velosity

AFR 205cc OR PRC 215cc that TSP sells?

I would say the AFR 205's seeing that the runners are smaller .

Wouldnt you need a flow bench to measure velocity?

I guess you could possibly extract a small idea by taking the flow numbers and comparing them to the intake runner size?????

For Example, saying if they both flow the same the one with the smaller intake port would probably have more velocity. Im streching here....
