Eliminate Blown Head Gaskets ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. Unlike many fasteners, they are heat-treated prior to thread rolling and machining. This ensures maximum clamp loads can be achieved and maintained without damaging the threads. Racers have relied on ARP head studs for maximum durability since the 1960's.
