What to seal head studs

to further Bill's comment, ARP fasteners ships all their stud kits with a special molly lubricant and instructions, what you put on the threads will affect the torque value, also torque spec for la blocks if i remember is 90, when using cometics or steel layers type gaskets and high compression engines, we always torque the studs closes to the lifter valley to 120 and the studs to the outside of the block to 110, to compensate for the longer inner stud length.....
