Cometic Chevy Small Block 4.165 inch Bore .120 inch MLS Head Gasket (w/All Steam Holes)

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed thickness of 0.120 inches and a 4.165-inch bore, making it a solid choice for rebuilding or upgrading your Chevy Gen-1 Small Block V8 engine. MLS gaskets are known for their ability to handle the demands of high-output engines because they are constructed from multiple layers of stainless steel, which gives them strength and resistance to corrosion. This design also allows the gasket to rebound and maintain a strong seal, even when mating different block and head materials like aluminum to cast iron.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating helps ensure a reliable seal across a variety of demanding conditions and surface finishes. The center layer is stainless steel and can be varied in thickness to meet specific engine build requirements. Because they are designed for maximum sealing performance, these MLS gaskets typically do not require any additional sealants, simplifying installation.

This gasket fits a wide range of Chevrolet and GMC vehicles from the early 1980s, including models like the Chevrolet C10, Camaro, and GMC C1500. It's a well-built component designed to provide dependable sealing for your engine.
