Cometic Chevy Small Block 4.165 inch Bore .080 inch MLS-5 Head Gasket (w/All Steam Holes)

If you're working on a Chevrolet Gen-1 Small Block V8 engine and need a new head gasket, this Cometic MLS gasket is a solid option. It's built with a 4.165 inch bore and a compressed thickness of .080 inches, designed to seal those high-output engines effectively. This gasket fits a wide range of 1980-1986 GM vehicles, including popular models like the Chevrolet C10 and GMC C1500.

Cometic uses a multi-layer steel (MLS) construction for these gaskets, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, meaning you don't need to use any extra sealants. The center layer is stainless steel and can be varied in thickness to meet specific engine requirements, like the .080 inch thickness on this particular gasket.

These MLS gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals. The inclusion of all steam holes helps with coolant flow and temperature management.
