Default ARP Main Stud Installation

Anyone know where I can find the instructions to install these? Or can anyone tell me off the top of their head? I just want to make sure I don't screw them up. I am wondering if I have to put moly lube on both ends of the studs, or just where the nuts go. I know the studs are only supposed to be finger tight without Loctite. Thanks!

Clean the bolt holes REAL well *duh* then lube up the bottom threads of the studs with the ARP moly lube and install them to finger tight until they bottom out in the holes. That's all there is to it. When you install the heads, you should lube each side of the washer, the top threads of the studs, and the inside threads of the nuts.

You guys need to figure out what one another is talking about. The title states "main studs" and the first answer explains how to install head studs. Ferocity02, are you talking about head studs or main cap studs????

LOL. der der derrrr... For some reason I always think head studs when I see ARP and studs in the same sentence.

MAIN studs, not head studs

Just finished putting a set in. Finger tight, torque inners to 50 ft./lbs then lossen and retorque to 50ft./lbs outers 60 ft.lbs (same sequence as inners) side bolts 19ft./lbs. Follow the regular tightening sequence of starting in the middle and working out in an "X" pattern.

Hope this helps

I believe it is 60 on the inners and 50 on the outers.

BTW - I have heard of align boring the mains after installing main studs. The machine shop I worked at always recommended it, said on some blocks, the mains would be "out of round" when swapping from bolts to studs. Strange.
