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 critcal because it sets the correct torque for the studs.
