Cometic Chevy Gen-1 Small Block V8 .045in MLS Cylinder Head Gasket - 4.125in Bore

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, ensuring a reliable seal between your cylinder heads and block without needing extra sealants.

Cometic uses multiple layers of stainless steel for 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, making it suitable for both aluminum and cast iron blocks. The center layer can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and a bore size of 4.125 inches, with an initial thickness of .045 inches.

This gasket is designed for a range of vehicles, including many Chevrolet C/K series trucks, Camaros, Corvettes, and GMC trucks from the early to mid-1980s. It features valve pocketed bores and steam holes for proper engine function.
