About this part

Product Details

When you're rebuilding the top end of your 1997-2004 Chevrolet Corvette, getting the cylinder heads seated correctly is critical. This Edelbrock head bolt kit, manufactured by ARP, is designed specifically for the Gen III LS1 engine and ensures a solid connection between your block and heads.

These bolts are cold-formed for molecular integrity and heat-treated before machining, giving them a strength rating of 170,000 p.s.i. The reduced diameter bolt heads are a smart touch, allowing you to re-torque the cylinder heads without needing to remove the valve train, which can save you a lot of time and hassle during assembly. Hardened and parallel-ground washers are included to provide a consistent clamping surface.

This kit is recommended for use with Edelbrock LS1 cylinder heads, but it's also a great choice for any rebuild using GM heads on your LS1 engine. Having the right hardware is key to a long-lasting, reliable engine build.
