The Cometic Chevrolet Mark-IV - GM Gen-V/VI Big Block V8 .095in MLS Cylinder Head Gasket - 4.570in Bore - C5433-095 is a precision-engineered head gasket with a 4.570" bore and .095" compressed thickness.
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.
