SBC S/S Head Bolt Kit 12pt.

The SBC S/S Head Bolt Kit 12pt. from ARP is the fastening solution serious small-block Chevrolet builders trust when maximum clamping force and reliability matter most. This kit is ideal for assembling street engines, weekend track cars, or high-revving performance builds.

Engineered to maintain consistent preload under extreme thermal and mechanical stress, this 12-point head bolt set replaces factory hardware with premium stainless steel fasteners. The stainless steel construction resists corrosion and offers superior strength compared to OEM steel fasteners, while the 12-point head design reduces socket slippage during installation and torque verification.

Each bolt in this kit is individually packaged and inspected to guarantee consistency, making it essential for any small-block Chevrolet rebuild or upgrade—including 283, 302, 305, 327, 350, 383, and 400 variants. This kit is perfect for applications ranging from mild street engines to aggressive forced-induction builds.
