Head Stud Kit GM LS Next Iron Block

The Head Stud Kit GM LS Next Iron Block by DART is designed for serious LS engine builders and high-performance mechanics who require reliability under extreme cylinder head clamping loads. This kit is essential for those building street engines, competition motors, or fresh rebuilds, addressing the critical need for secure head fastening in aftermarket LS applications.

Unlike traditional head bolts, the head studs in this kit eliminate the risk of thread stripping in the block and provide superior clamping force consistency. They are precision-machined fasteners that thread into the block and accept a nut at the cylinder head surface, distributing clamping force evenly while preventing potential galling or cross-threading. The kit includes all necessary studs along with matching hardened washers and nuts, designed to account for thermal expansion differentials between iron block material and aluminum heads.

This stud kit is particularly beneficial for any LS Next Iron Block build that exceeds stock specifications, including those utilizing nitrous or other forced induction methods. DART's design ensures proper engagement with the specific bore geometry and thickness of these cast blocks, maintaining optimal preload across all eight cylinder positions for enhanced performance.
