Cometic Chevy Small Block 4.125 inch Bore .036 inch MLS Head Gasket (w/All Steam Holes)

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines with a 4.125 inch bore. It features a compressed operating thickness of 0.036 inches and includes all steam holes, which help manage heat in the engine block. MLS gaskets are well-built for high-output engines and don't require any additional sealants, making installation more straightforward. They work well with both aluminum and cast iron blocks, resisting the shearing forces that can occur between different metals.

The construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit, which is designed to handle tough sealing conditions and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses, like the 0.036 inches found in this specific gasket.

This gasket fits a wide range of vehicles from the early 1980s, including models like the Chevrolet Camaro, GMC C1500, and Buick Century. If you're rebuilding the top end of your small block Chevy, this gasket offers a solid option for reliable sealing.
