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 acilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters.
