Edelbrock BBC Head Bolt Kit

Starting with bolts cold-formed to ensure molecular integrity and heat-treated before thread rolling and machining, this Edelbrock head bolt kit is built for serious performance. These bolts are rated at 170,000 p.s.i., giving you a strong foundation for your Big-Block Chevrolet engine build. The reduced diameter bolt heads are a smart design choice, making it easier to re-torque your cylinder heads without having to remove the valve train, a common headache during engine maintenance.

This kit is specifically designed for 1965-90 Big-Block Chevrolet Mark IV engines, including displacements from 396 up to 502 cubic inches. It's important to note that these are intended for use with specific Edelbrock Performer and RPM cylinder heads, and are not compatible with stock heads. You'll also find that the included hardened and parallel-ground washers are essential for proper load distribution, ensuring your cylinder heads stay securely in place under demanding conditions.

If you're working on a classic Chevrolet like a Bel Air, Impala, or Chevelle from the mid-60s to the mid-70s, or even a later model C/K series truck from the 90s, this kit offers a well-built solution for your engine's top end. It’s a solid option for anyone rebuilding or upgrading their Big-Block Chevy.
