ARP Pontiac 400-455 w/ Edelbrock D-Port Head Stud Kit

This is the ARP 190-4306 head stud kit, specifically made for Pontiac 400 and 455 cubic inch engines that are fitted with Edelbrock D-Port cylinder heads. When you're rebuilding the top end of your engine, especially with aftermarket heads like these Edelbrocks, using a quality head stud kit is a smart move. These studs help ensure a consistent and even clamping force across the cylinder head gasket, which is crucial for sealing and preventing leaks.

ARP is well-known for making strong engine components, and this kit is no exception. The studs are manufactured from high-grade alloy steel, heat-treated, and then centerless ground for a perfect fit. This level of care in manufacturing means they're built to handle the stresses of combustion and temperature changes. Unlike head bolts that you typically torque down once, head studs allow for more precise control over the clamping force and can be torqued multiple times without stretching or weakening, which is a big plus if you ever need to pull the heads again.

This kit includes the necessary studs, nuts, and washers, all designed to work together for a reliable installation. Make sure to follow ARP's recommended torque specifications and lubrication procedures when installing these studs to get the best performance and longevity out of your engine build.
