What material are these head bolts made from?

These head bolts are made from strong 8740 chromoly steel, a material known for its ability to withstand high clamping loads. This ensures a reliable seal for your cylinder heads.

Why do these bolts have 12-point heads?

The 12-point heads offer improved access for your socket wrench, especially in tight engine compartments. This makes installation and tightening more convenient compared to standard 6-point bolts.

Does this kit include everything needed for installation?

This kit includes the head bolts and ARP Ultra-Torque fastener lubricant. It's recommended to consult your engine's service manual for any additional hardware or specific installation procedures.

Product Details

If you're rebuilding the top end of your Small Block Chevy engine, especially if you're looking for a solid way to secure your cylinder heads, this ARP head bolt kit is a popular choice. These bolts are designed to replace the factory bolts and provide a more reliable clamping force, which is crucial for sealing the combustion chamber and preventing leaks.

ARP uses 8740 chromoly steel for these bolts, which is a strong material that can handle the high clamping loads required for performance engines. The 12-point heads on these bolts make them easier to access and tighten with a socket, especially in tight engine bays where a standard hex head might be difficult to get to. They also come with a black oxide finish to help resist corrosion. ARP includes a packet of their ARP Ultra-Torque fastener lubricant, which is specifically formulated to ensure accurate torque readings when you're installing them.

When installing these, it's important to follow the torque sequence and specifications provided by ARP. Proper installation ensures the bolts stretch to their designed length, providing the correct clamping force. This kit is a well-built option for anyone looking to ensure their cylinder heads are securely fastened.
