calling all head guru's !!!! which heads will produce better gains

well i have seen flow numbers showinf that professinally ported e7te's can flow better then a stock gt40 or gt40p head, although then again if you port those they can flow better, over at powerheads, they say that they can port a e7te to out flow a ported p head, haven't seen the flow numbers of that comparision but if its true thats quite the acomplishment..

if your goign to port one i feel it is best to port the other, that way the ports will match up perfectly..

I would go for the GT-40P's.

Since thread is MONTHS old now, I guess my opinion won't matter much, but I too would go GT40P's without a doubt.

Power heads says 217/174 cfm. I'm putting on P heads.
