Cometic Chevy Gen1 Small Block V8 .034in MLS Cylinder Head Gasket - 4.125in Bore - 18/23 Degree Head

Cometic Gasket is well-known for making robust sealing solutions, especially their multi-layer steel (MLS) head gaskets. This particular gasket is built for Chevy Gen-1 Small Block V8 engines and features a 4.125-inch bore, designed to handle the demands of higher output applications. It's constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, ensuring a solid seal without needing additional sealants.

This MLS design is ideal whether you're pairing aluminum heads with an aluminum block or cast iron block. The multi-layer construction allows the gasket to rebound and resist the shearing forces that can occur between different metals. The center layer is stainless steel, and the overall compressed thickness is about 0.036 inches, with an uncompressed thickness of 0.034 inches. This gasket also includes steam holes, which help manage heat and pressure within the engine. It fits a wide range of vehicles, including many Chevrolet C/K series trucks, Camaros, and Monte Carlos from the early to mid-1980s.
