head studs
i just got an engine rebuild done and i have ARP head studs on the one website i am looking at it says to torqye all of the studs to 90ft lbs except for the two shorter head studs i says to only torque them to 7-9 ft lbs does that make sense to do that?

Use angular torquing method on heads which means torque toapprox 60% of goal on all bolts in pattern and then repeat procedureincrementing by 10 ft lbs each time until you reach spec torque of 90ft lbs. I started at 50 and worked up through 60, 70, 80, and then 90.For head bolts, the manual states to start at 29 ft-lb on each, then gostraight to 90 ft lb. Loosen all bolts completely, and then do itagain. Torque in the order shown in Image 18 for the driver'sside head. The same pattern is used on the passenger head.with 5 &8 being at the back of the engine and 6 & 7 at the front.
Don't forget the two small M6 bolts. One on each head. Torque to 7-9 ft. lbs. (1.0 - 1.2 kg-m)
