I forgot to mentioned the head studs are ARP. I just need to know what torque value on the final pass or where I can get this information.

Thanks

I used three passes on the large bolts using ARP Moly Lube 35-55-80 ft. lbs.
Once that sequence is complete I did the small ones in proper sequence to 22 ft. lbs.

Are torque values the same for bolts vs studs?

vsocks1 is using ARP studs, so the tq values he posted are for the nuts...exactly what you are looking for.

The studs themselves get no torque...run them down till they bottom out, that's it. Do not try to tighten them beyond that, or you risk cracking the block.
