ARP SB Chevy Dart Buick head stud kit

If you're rebuilding the top end of your small block Chevy, Dart, or Buick engine, a strong set of head studs is crucial for keeping everything sealed up tight. These ARP head stud kits are a popular choice for serious engine builders because they offer a significant improvement over stock head bolts. They ensure consistent clamping force across the cylinder head, which is vital for preventing blown head gaskets, especially when you're pushing the limits with higher compression or boost.

ARP uses high-grade alloy steel for these studs, heat-treated to a tensile strength of 200,000 psi, which is considerably stronger than most factory bolts. This means they can handle the increased cylinder pressures and temperatures that come with performance modifications. The threads are rolled after heat-treat, which makes them stronger and less prone to stripping than cut threads. You'll also notice the black oxide finish, which helps prevent corrosion and makes them easier to clean up during assembly. This kit includes the necessary studs, nuts, and washers, all well-made to ARP's standards.

When installing these studs, remember that they are designed for a direct replacement of your stock head bolts. It's important to chase the threads in your block to ensure they are clean and free of debris before installation, as this helps achieve accurate torque readings and prevents damage. Using the ARP assembly lube provided with the kit is also key to getting the correct clamping force.
