Product Details

These Edelbrock head bolts are cold-formed to ensure molecular integrity, a solid starting point for any engine build or rebuild. They're heat-treated before thread rolling and machining, giving you a well-built fastener that can handle the stresses of a performance engine. The bolts are rated at 170,000 p.s.i., providing strong clamping force for your cylinder heads.

A notable design feature is the reduced diameter bolt heads. This smart detail means you won't have to remove your valve train to re-torque the cylinder heads, saving you time and hassle during maintenance. Hardened and parallel-ground washers are included to ensure even pressure distribution under the bolt heads.

This kit is designed for 1963-96 small-block Ford 289 and 302 engines, fitting a wide range of vehicles like the Ford Bronco, F-150, and Country Squire. It includes 7/16" bolts and the necessary #9680 bushings for a complete installation.
