factory torque settings are at 54 ft lbs, which if you know a thing or two about motors, is very very low for a motor like a 7mgte.
my arp head studs came with instructions to torque them to 83 ft lbs, and thats with the grease provided which actually increases the torque again.
stock gasket with arps and correct torque will be fine.
or go hard like me and go hks metal headgasket to boot.
