Max boost for stock head gasket and arp2000 (425's)
#1
#10
A ported head will flow more and make more power at lower boost because it is moving more air. This is assuming you have the ful o make more power. Boost alone does NOT make power if it isn't at the smoke point.
I ran 55 lbs boost with my 02 and compounds with stock gasket and over torqued stock head bolts.
