If memory serves me correctly...
big bolts:
25 50 70 in a circular pattern from center
small bolts
15 - 30 inside out.

A quick word of warning here, some have found the ARP bolts bottom in the holes in the block and a few have broken as a result. If you haven't done so, do a quick check on length.

Aren't these torque-to-yield bolts? You go to a certain torque value and then finish by tightening a certain number of degrees??
