The Cometic GM LS9/LSA Gen-4 Small Block V8 .052in MLX Cylinder Head Gasket - 4.100in Bore - RHS - C5985-052 is a precision-engineered head gasket with a 4.100" bore and .052" compressed thickness for the Right-Hand Side (RHS).

The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring MLX Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers for superior sealing under extreme cylinder pressures and temperatures. 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.
