Torque 65 ft lbs to a max of 70 ft lbs. Head studs or bolts too tight will do more harm than good.
Small head 6 point ARP Bolts with washers. Head gasket of your choice.
For those who asked;
You do not want a stud installed in a block tight. I usually screw down by hand and back off by 1/4 turn and use a copper base anti-sieze on the threads lightly.
