turbo or procharged hi port combos
im sure there are a few but any hands on combos using the hi ports? it seems generally many are opting for the e heads. I assume its due to possibly better casting quality and or the added height the hiport puts the intake manifold and exhaust ports. are there any other reasons i may not be aware of? KRE has a variety of porting and chamber options so i know its not that.
gto george obviously has abused a set of hi ports, with a roots blower. thanks

I think the high port would work fine . just keep it as a stock port , no porting besides a match port to the intake.
People probably just go with the E head because it was the first one being used from the beginning, so its just been proven. You know how that goes .. I think the high port would be a nice combo...

Old bathtub style chamber the e-heads have are more forgiving (larger tuning window) vs kre fast burn style. I'd guess that's a reason also

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
