Can someone confirm 100% how much to torque ARP HEAD STUDS in ft-lb? (preferably from an instruction sheet) Also do u need to use moly lube?

i used moly lube from repco as nobody else had any(not arp).. we tightened them to 60ft even though below says slighty different.. make sure u go through the same procedure that it says in holden book.. tighten to a certian amout then tighten firmer again.. then loosenn all the way then copy-tighten to a certian amout then tighten to the final setting.. make sure u do it in the right order of bolt numbers... .. Some original photos have not been recovered yet.

Just use the standard Holden recommendations, if you're using moly lube... if your not using lube, then add another 5-10 ft/lbs to the final torque setting but leave the rest the same.
