It is one of the first upgrades performed on an engine that will be tuned for increased power, as the head gasket is one of the first points to fail.\u003c\/p\u003e\u003cp\u003eThey are manufactured from Custom Age 625+, a superalloy with a typical tensile strength of 260,000 to 280,000 psi, which is highly resistant to fatigue and corrosion. The threads are rolled after heat treatment, which gives ARP studs superior fatigue strength, and the final grinding ensures the cylinder head and gasket seat perfectly aligned during installation.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque specifications, as the load received by each part will not be the same with a different lubricant.
