Head Stud Kit - 6pt BBC Dart Block w/Dart Heads

The Head Stud Kit - 6pt BBC Dart Block w/Dart Heads from ARP is the foundation of any serious high-performance big-block Chevy build. Head studs are the critical fastening system that clamps your cylinder head to the block, and unlike conventional bolts, studs provide superior clamping load consistency and repeatability—essential when dealing with aggressive boost, nitrous, or high-compression naturally aspirated applications. This kit is engineered specifically for Dart's precision-ported BBC blocks paired with Dart cylinder heads, ensuring exact fit and optimal clamp load distribution across all combustion events.

ARP's 6-point studs are manufactured from premium alloy steel and feature a proprietary thread design that resists loosening under extreme thermal cycling and vibration. The 6-point head geometry distributes load across a larger contact area than standard fasteners, reducing the risk of head lift, gasket failure, and catastrophic coolant leaks under sustained high-boost conditions. Each stud in this kit is individually packaged and arrives with the proper washers and nuts required for installation, eliminating guesswork and ensuring you have a complete, matched set ready for torque sequencing to ARP's specifications.

Whether you're building a street/strip big-block Chevy, a dedicated drag engine, or a turbocharged power plant, this head stud kit is non-negotiable for long-term reliability above stock power levels. Installation requires removal of the cylinder head and careful torque sequencing in a crisscross pattern to achieve uniform gasket seating. The ARP 235-4117 kit weighs 7.5 pounds and ships in compact dimensions, making it easy to integrate into your engine assembly sequence alongside your Dart block and head combination.
