(1) To ensure proper thread engagement and accurate torque readings, clean and re-tap ALL threads in the block. Re-tap only if necessary.
(2) Clean and inspect all hardware prior to installaion. Look for obvious defects or shipping damages, plus proper fit, length and dimension.
(3)A. If cylinder head studs protrude into water jacket, lubricate block threads of the studs with ARP THREAD SEALER.
B. If cylinder head studs protrude into blind hold, lubrcate threads, nuts & washers with ARP MOLYASSEMBLY LUBRICANT or 30wt. Motor oil.
C. Screw studs into block "HAND TIGHT ONLY".
NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERED.
THE FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP.
(4) Install cylinder heads and check for binding or misalignment.
(5) ARP recommends using ARP MOLY LUBRICANT or at the very least, a good quality Moly Lubricant as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil (or low quality lubricant) is used.
Torque values are based on 75% of the fasteners yield strength. Use the manufacturerstorque sequence but do not use the engine manufacturers torque specs. Torque the nuts to 80 ft. lbs for ARP MOLY ASSEMBLY LUBRICANT (or ARP THREAD SEALER) or torque to 120 ft. lbs with 30wt. Motor oil.
Note: Do not use any other Moly Lube. Use only ARP MOLY LUBE or head gasket failure can result.



This is what I went by. I went 120 and have not had any problems. 65 seems pretty low.
