Cometic Chevrolet Gen-1 Small Block V8 .045in MLS Cylinder Head Gasket - 4.200in Bore

Starting with a multi-layer steel (MLS) construction, this Cometic head gasket uses embossed outer layers coated with Viton, a heat-resistant rubber material rated up to 482°F. This design is built to handle the demands of high-output engines and works well with both aluminum and cast iron blocks, even when mating aluminum heads to cast iron blocks. The compressed operating thickness is a precise 0.045 inches, and the 4.200-inch bore diameter is suitable for many Chevrolet Gen-1 Small Block V8 applications.

The multi-layer stainless steel design provides increased strength and the ability to rebound, helping to resist corrosion and maintain a strong seal. Unlike some older gasket types, these MLS gaskets don't require any additional sealants, making installation more straightforward. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, offering flexibility for specific build requirements. These gaskets are also designed with undersized water ports, allowing for customization when using aftermarket heads.

This gasket fits a wide range of vehicles, including popular models like the Chevrolet C10, Camaro, and Corvette from the 1980s, as well as many Buick and GMC trucks and cars from the same era. It's a solid option when you need reliable sealing for your Gen-1 Small Block V8 build.
