This stud kit now comes complete with Z1 Custom Head Stud Washers!!
Head Stud Torque Spec's :100 ft-lbs w/moly lube on & under nut.
Z1 recommends using the supplied ARP Moly Lube when torquing ARP fasteners.
Procedure for Installing Head Studs: Finger tighten all the studs into the block once to make sure they fully seat. Make sure to put the 2 shorties in the correct places. Remove each and apply red loctite to the threaded ends going into the block and screw them back into place fully seated again. Install the heads. Install washers on all studs. Apply the ARP moly lube to each nut on the threads and bottom contact surface. The ARP lube is critical because it sets the correct torque for the studs. Use of other lubricants will require other unknown torque values. Torque each to 100 ft-lbs in the pattern and manner noted in the factory service manual 3 times.
Kit includes:
- (16) head studs and nuts
- (1) pack of ARP moly lube
