see, alot of people argue that, but i have seen flow #'s on both ported and unported and they are pretty damn close.... the PI's flow a tad higher at high lift and the non PI's flow a bit better at lower lifts........
i was just saying for alot cheaper you can do the PI cam and intake and have a good gain in HP for 1/3 rd the cost, and not having to deal with taking the heads off and such........
the PI swap will make more power overall, but this is mainly from the boost in CR which will be bad when running a power adder later, and the PI swap is alot more in $$$$
i'm not knocking the PI's, just giving the guy a different option........
