Edelbrock head bolt kit for 1997‑on Chevrolet Gen III LS1 engines fits Edelbrock and GM LS1 cylinder heads and includes head bolts and matching washers for two heads. Hardware is cold-formed and heat-treated before thread rolling, with reduced-diameter bolt heads to allow cylinder head re-torque without valve train removal. Hardened washers provide stable clamping, and ARP manufacturing is specified.
