It replaces the stock head bolts with studs and nuts, a solution that distributes the load more evenly across the gasket and prevents wear on the block threads each time the cylinder head is removed.\u003c\/p\u003e\u003cp\u003eThey are manufactured from 8740 chromoly steel, heat-treated by ARP to a tensile strength of approximately 190,000 psi. The threads are rolled after heat treatment, which gives ARP studs superior fatigue resistance, and final grinding ensures that the cylinder head and gasket are properly aligned during assembly.\u003c\/p\u003e\u003cp\u003eFollow the torque specifications and sequence in the ARP instructions, which are calculated for their assembly lubricant; using engine oil will change the actual torque.
