Product Details

These head bolts are cold-formed to ensure their molecular integrity, a solid choice when you're rebuilding the top end of your Ford 351 Cleveland engine, especially when paired with Edelbrock Performer RPM cylinder heads. The bolts are heat-treated before thread rolling and machining, giving them a strong rating of 170,000 p.s.i. This kit is designed to fit a range of vehicles from the late 60s and early 70s, including popular models like the Ford Mustang, Torino, and Mercury Cougar.

A notable design feature is the reduced diameter of the bolt heads. This practical detail means you won't have to remove the valve train when it's time to re-torque the cylinder heads, saving you a bit of hassle during maintenance. You'll also find hardened and parallel-ground washers included in the kit, ensuring a consistent and even clamping force across the cylinder head surface.

This kit comes with all the necessary head bolts and washers for a pair of heads, making it a complete package for your engine build. They are manufactured by ARP, a well-known name in high-performance engine components.
