The Cometic GM LT5 Gen-2 Small Block V8 .089in MLS Cylinder Head Gasket - 4.155in Bore - RHS - 1990-1995 - C5264-089 is a precision-engineered head gasket with a 4.155" bore and .089" compressed thickness for the Right-Hand Side (RHS).

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. 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.
