Going by your theory, then how come the guys that are hitting 25psi etc are not popping gaskets all the time?
Head gaskets
I am at 35 to 36psi with special 95 M90 blower with teflon seals we have no head gasket issues. Now the reason why I have an O-ringed block with receiver grooves in the heads with copper head gasket with Donovan head studs. I have special tooling made for the setup using Fel Pro head gaskets or multi layer is not the best way to go at all. Now I have kooks long tube headers its best to intall them without the driverside head on. The passengers side is easy with head on to install through the bottom side
