About this part

Product Details

This is the ARP 12-point head bolt kit for Small Block Chevy Gen III and LS engines built in 2003 and earlier. If you're rebuilding the top end of one of these engines, especially if you plan on running more power than stock, a strong set of head bolts is crucial for keeping your cylinder heads sealed down tight under pressure. ARP is well-known for making robust engine hardware, and these bolts are a solid choice for ensuring reliable performance.

These head bolts are made from forged 8740 chromoly steel, which is a strong material that can handle the clamping forces needed for performance applications. The 12-point head design is a practical touch, allowing for easier access and tightening in tight engine bays compared to traditional 6-point bolts. ARP includes a packet of their ARP Ultra-Torque fastener lubricant, which is important for achieving accurate torque readings and preventing galling during installation. Following the manufacturer's recommended torque sequence and values is key to a successful rebuild.
