What is the main advantage of using head studs over head bolts?

Head studs allow for more accurate and repeatable torque readings when installing cylinder heads. They also prevent damage to the threads in your engine block if you need to remove the heads multiple times.

What material are these ARP head studs made from?

These studs are manufactured from ARP's proprietary 8740 chromoly steel, which is heat-treated to achieve a tensile strength of 200,000 psi.

Does this kit include everything needed for installation?

This kit includes the ARP head studs, nuts, and washers. It is recommended to use ARP Ultra-Torque lubricant for accurate torque application, which may need to be purchased separately.

Product Details

When you're rebuilding the top end of your small block Chevy, you want the cylinder heads to seal tight and stay that way. This ARP 18A standard head stud kit gives you just that. You get a complete set of ARP's well-known head studs, along with the necessary nuts and washers, all designed to work together for a secure cylinder head installation.

ARP studs are made from their proprietary 8740 chromoly steel, heat-treated to achieve a tensile strength of 200,000 psi. This means they can handle the clamping forces needed to keep your heads sealed under pressure and temperature changes. Unlike stock head bolts that you might torque down once, head studs allow you to repeatedly torque and detorque your cylinder heads without damaging the threads in your block. This is a big help if you need to pull the heads again for any reason, like checking valve lash or making adjustments.

This kit is for standard bore small block Chevy engines. Make sure to follow ARP's installation instructions carefully, which typically involve cleaning the block threads and using their ARP Ultra-Torque lubricant for accurate torque readings. A proper installation ensures the best possible seal and longevity for your engine build.
