Product Details

This ARP SB2-2 head stud kit includes everything you need to securely fasten your cylinder heads to the engine block. You get the studs themselves, along with the necessary nuts and washers, all designed to work together for a reliable seal. These studs are specifically made for SB2-2 blocks and feature a 3/8 inch diameter with a 260,000 psi tensile strength, offering a strong and dependable connection for your engine's top end.

When you're building or rebuilding an engine, especially one that will see demanding use, the integrity of the head gasket seal is paramount. These ARP studs are well-built from premium 8740 chromoly steel, a material known for its strength and durability under high stress. The 12-point nuts are a practical touch, making them easier to torque down in tight engine bays compared to traditional hex nuts. ARP is a well-known name in performance engine components, and this kit reflects their commitment to providing solid options for serious engine work. The 260ksi rating means these studs can handle significant clamping force, which is crucial for preventing head lift and maintaining a consistent seal under high cylinder pressures.

Proper installation is key to getting the most out of this head stud kit. Always follow the manufacturer's instructions for cleaning the block and head surfaces, and ensure you use the correct thread sealer and lubricant as specified by ARP. This kit is designed for a direct fit on SB2-2 blocks, simplifying the installation process. Ensuring a strong, even clamping force across the cylinder head is vital for preventing leaks and maintaining engine performance over time.
