It is one of the first upgrades made to an engine that is going to have its power increased, because the head gasket is one of the first points to fail.\u003c\/p\u003e\u003cp\u003eThey are manufactured from ARP2000, an alloy proprietary to ARP that reaches about 220,000 psi of tensile strength and maintains its properties under heat better than chrome-moly. ARP precision-grinds each stud after heat treatment to ensure it is straight and concentric, and threads are rolled after the heat treatment process; this results in a fatigue strength roughly twenty times greater than that of a thread cut before heat treatment.\u003c\/p\u003e\u003cp\u003eFollow the torque specifications and tightening sequence in the ARP instructions, which are calculated for their assembly lubricant; using motor oil will change the actual torque.
