ARP SB Chevy Dart II head stud kit

Starting with a 12-point, 1/4 inch socket head on the stud, ARP's 234-4509 kit is built for Small Block Chevy engines using Dart II blocks. These studs are made from ARP's proprietary 8740 chromoly steel, which is heat-treated to give them a tensile strength of 200,000 psi. This means they can handle the clamping forces needed to keep your cylinder heads sealed tight, even under high compression or boost.

When you're rebuilding the top end of your engine, especially with a performance block like the Dart II, using quality head studs is crucial. These studs provide a more consistent and accurate clamping load on your cylinder head gaskets compared to stock head bolts. This improved sealing helps prevent blown head gaskets, which can lead to serious engine damage. The kit includes the necessary studs, nuts, and washers, all well-made to ensure a proper fit and reliable performance.

For a secure and long-lasting seal on your performance Small Block Chevy, this ARP head stud kit is a solid option. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures to get the best results from these high-strength fasteners.
