I was told by an engine builder to put a tiny amount of anti-sieze on the flange of the bolt head, that contacts the face of the cam gear. Just finished an unexpected blown head gasket on my engine with less than 5K miles on her. Apply liquid Teflon to all head bolts that protrude into coolant passages. For 8mm head studs, torque the cylinder head nuts to 18 ft-lbs. Here is the head gasket laid in place, ready for the cylinder head. Torque to 70 ft/lbs. The drop in version of that is SUM-8712. What should the torque sequence of cylinder head bolts be for 454 7.
