    The head bolt torque totally depends on what lube that you use on the head bolts. Use 30w oil, and it is much higher than if you use ARP lube.

    On a 502, using ARP bolts, with ARP lube, the Tq for all the bolts is 65 lbs. If you use 30w oil, on the same bolts the torque is 85 lbs. Needless to say, this is done in 3 or 4 steps,(35-50-65) (30-45-65-85) and according to the correct GM pattern.
