Description

The Stage 8 8931B is a locking header bolt kit designed for GM V6 and Small Block Chevy engines. This set includes 12 bolts with a 3/8-16 thread size and a 1-inch length. The bolts feature a 12-point head style and are made from Grade 8 steel with a nickel-plated finish.

Stage 8's patented system utilizes a grooved hex-head bolt, a retainer, and a snap clip to ensure the bolts remain securely in place. This design prevents them from backing out, thereby eliminating header leaks and blown gaskets caused by loose fasteners.
