Do I need an AFTERMARKET HEAD GASKET

[paintball12k]

I have an EVO III turbo, Greddy FMIC, 660cc Injectors, fuel pump


Do I need a aftermarket head gasket. My goal it to run about 22psi at the track and 15 or 16 on the street.

I'm just looking to get somewhere around 350 hp. Is an Aftermarket head gasket worth buying or will the stock head gasket do.

What thickness for an aftermarket head gasket is good?

Throw in some ARP head studs and you should be golden....given you don't "knock" it loose.

The OEM hg will go a long way. If you dont knock, then 22psi on an Evo 16g would likely be fine even on an OEM HG, that would put you in the 38lb/min or so range. For extra safety properly install some ARP's.
