Cometic Chevy Gen-1 Small Block V8 .056in MLS Cylinder Head Gasket - 4.200in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It features a bore size of 4.200 inches and an overall thickness of .056 inches, with a compressed operating thickness of .036 inches. These gaskets are built to handle the demands of high-output engines, offering maximum sealing performance without needing additional sealants.

Constructed from multiple layers of stainless steel, these MLS gaskets offer increased strength and the ability to rebound, which helps resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various load conditions. The center layer is stainless steel, allowing for different thickness requirements. This construction makes them suitable for applications with aluminum heads on either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.

This particular gasket is designed with valve pocketed bores and steam holes, and it's intended for use with World Products Man-o-War blocks. It fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.
