Cometic Chevy Gen1 Small Block V8 .040in MLS Cylinder Head Gasket - 4.200in Bore

Starting with a compressed thickness of 0.040 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. It’s constructed from multiple layers of stainless steel, which gives it strength and helps it rebound to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and works well with different head and block materials, including aluminum to aluminum or aluminum to cast iron. This makes it a solid choice for high-output engines where reliable sealing is critical.

The design of these MLS gaskets means they don't require any additional sealants, simplifying installation. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the 0.040 inch compressed thickness on this particular gasket. This gasket is specifically designed for a 4.200 inch bore and is noted as suitable for Brodix BD2000 heads, but it fits a wide range of Chevrolet Gen 1 Small Block V8 vehicles from the early 80s, including models like the Chevrolet C10, Camaro, and GMC C1500.
