The stock head gasket is good for 14.7 psi (1 bar) boost, no need for a metal gasket --


So Stock head gasket and ARP head studs will be fine for 10-18 psi? or is 14.7 psi the hard-limit for the stock gasket even with stronger head studs?

And that valve looks like that after 5min on a power drill with a round of 240grid removing the worst and outer most layer... It were some kind of mineral build-up? Like calc or something else don't know...
