Cometic Chevrolet Gen-3 Inline 6 .051in MLS Cylinder Head Gasket - 4.125in Bore

This product is a Cometic Multi-Layer Steel (MLS) head gasket specifically for Chevrolet Gen-3 Inline 6 engines. It has a 4.125-inch bore and a compressed thickness of 0.051 inches. This gasket is built with multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material. This construction helps ensure a strong seal, even with aluminum heads on cast iron blocks, and it doesn't require any additional sealants.

The multi-layer design gives this gasket increased strength and resistance to corrosion. The Viton coating on the outer layers is designed to handle harsh sealing environments and varying surface finishes, making it suitable for high-output engines. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.051 inches found in this particular gasket. This gasket fits a wide range of vehicles, including models like the 1968-1971 Buick Skylark, 1963-1973 Chevrolet Bel Air, and 1965-1979 Checker Marathon.
