Just to be clear you can't use the stock head bolts again as they are TTY bolts and once used they are are done and you will have to buy a new set. If using the ARP head bolts they can be used again.

The TTY or stock bolts have a poundage torque followed by an angle torque as where the ARP bolts are a 30-60-90 lb torque sequence. Running a MLS head gasket does not require a change in the torque values. Hope this helps!
