The Edelbrock Cylinder Head Bolt Sets are manufactured by ARP and are cold rolled and heat-treated prior to thread rolling and machining. They feature reduced diameter bolt heads eliminating the need for valve train removal when re-torquing cylinder heads and permit the use of larger diameter springs. Each complete set of head bolts is of the highest quality and includes hardened and parallel-ground washers. These bolts are rated at 170,000 PSI.
