ARP SB Chevy w/12-Rollover Brodix head bolt kit

This is the ARP 234-3703 head bolt kit, specifically made for Small Block Chevy engines that are using Brodix heads with a 12-rollover bolt pattern. ARP is well-known for making strong fasteners, and this kit is no exception. It’s designed to give you a reliable way to secure your cylinder heads to the engine block, which is crucial for proper engine sealing and performance.

What makes this kit stand out is its construction and the specific application it’s built for. These bolts are made from ARP's proprietary 8740 chromoly steel, which is heat-treated to ensure it can handle the clamping forces needed for high-performance engines. The kit includes hardened parallel ground washers, which are important for ensuring even load distribution across the cylinder head deck. This helps prevent distortion and ensures a consistent seal between the head and the block, especially when you're dealing with the pressures and temperatures found in a modified engine. The 12-rollover bolt pattern is a specific detail for certain Brodix heads, so using the correct kit like this one is key for a proper fit and seal.

When you're rebuilding or upgrading the top end of your engine, using quality head bolts like these from ARP is a smart move. They are built to last and provide the clamping force you need for reliable operation. Make sure to follow the manufacturer's torque-to-yield specifications during installation to get the best results.
