The Cometic GM LSX Gen-4 SB V8 .071in DST Cyl. HG - 4.165in Bore - 1/2in & 3/8in Studs - RHS - C15743-071 is a precision-engineered head gasket with a 4.165" bore and .071" compressed thickness for the Right-Hand Side (RHS).

The Cometic Dynamic Seal Technology (DST) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Dynamic Seal Technology (DST) construction, this gasket uses a proprietary multi-layer design with an elastomeric sealing bead that provides consistent clamp load retention. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
