BBC S/S Head Bolt Kit 12pt.

The BBC S/S Head Bolt Kit 12pt by ARP is designed for big-block Chevrolet engine builders and serious automotive enthusiasts who demand maximum reliability in extreme conditions. This kit is ideal for those building high-performance engines, whether for street use or competitive racing.

Manufactured from premium-grade alloy steel, these fasteners are engineered to replace factory head bolts in big-block applications. The proprietary micropolish finish ensures consistent torque values and reduces galling during installation, while the 12-point socket head design enhances grip and minimizes the risk of rounding off fasteners.

It is compatible with Gen I and Gen II BBC platforms, making it a critical component for high-performance street rods, muscle cars, and dedicated race engines.
