Cometic Chevy Gen-1 Small Block V8 .051in MLS Cylinder Head Gasket - 4.200in Bore

Cometic Gasket is well-known for making multi-layer steel (MLS) head gaskets that seal well in high-output engines. This particular gasket is built for Chevrolet Gen-1 Small Block V8 engines and features a 4.200-inch bore. It's designed to handle the demands of modern engines without needing extra sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The compressed thickness is 0.036 inches, and the center layer can be varied to meet different thickness needs. This design is suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal from the early to mid-1980s. It's a solid option if you're rebuilding the top end of your Gen-1 Small Block V8.
