Manufactured by ARP, Edelbrock head bolt kits contain a complete set of the highest quality head bolts and hardened washers available. They are cold-formed to ensure molecular integrity and heat-treated prior to thread rolling and machining. Reduced-diameter bolt heads eliminate the need for valvetrain removal to facilitate cylinder head re-torquing. Hardened and parallel-ground washers are included, and they're rated at 170,000 psi.

Wrong instructions caused a big problem

Summit RacingSummit Racing Verified Purchase

EDL-8550
Update: ARP stepped up, that's what counts. A human somewhere messed up, but ARP is upgrading me from bolts to studs, sending me new lube, thread sealer. I didn't ask, but they threw in a tee shirt and a cap. People make mistakes, as long as they make it right. Old review follows: Well someone at ARP messed up. Right bolts, wrong instructions, said to torque to 100 ft lbs. The correct torque is apparently 65 ft lbs. Broke 2 bolts......... It was NOT Summit's fault, but they stepped up, sending me new bolts and new head gaskets at no cost. Summit gets 10 stars out of 5. ...read more
