My recipe was OEM Mitsu composite HG with early head bolts, not studs over torqued to about 110 to120 ft-lbs.

With good surfaces my car never pushed coolant even at 40 psi. Boost with detonation will leak regardless of what configuration used. You need a solid tune if you are running big boy boost.
