what is the torque spec on bolting head down on ARP head studs (if different from the manual and stock head studs)
same question on procedure, tightening pattern (again if it is different from stock head studs)

I cleaned my thread holes in the block with brake cleaner and used loctite on the ARP head studs into the block. Same pattern and torque spec as stock

Clean all taped holes thoroughly, apply Teflon Sealer if holes are open to coolant, or Oil if holes are blind.
Install studs hand tight.
Apply Moly lube to threads and washers both sides.
Torque using factory Proceedures and specs BUT in increments of 15-25-38 ignoring the degrees past 14-ft-lbs
This includes the small outside bolts FACTORY SPECS which go to 10 ft-lbs
Now go back in the proper sequence, One at a time, loosen the nut 1/4 turn and retorque to final spec in one motion, in this case 38 lb.ft. and 10 lb.ft.
You will see that the nut goes past where it was by up to 1/2 turn and you are not exceeding any torque values.
I wrote on this as I had a problems with ARP in the past. Here is the thread
