washers

The studs are manufactured in ARP’s Santa Paula, CA plant, with threads rolled after heattreat
to provide optimum fatigue strength. They are centerless ground to assure perfect
concentricity. The ends of the studs are broached to facilitate easy installation. This feature
also enables the cylinder head to be removed in tight quarters.
