Cometic Chevy Small Block All 12-23 Deg. Head 4.200in Bore .080in MLS Head Gasket

If you're working on a Chevrolet Gen-1 Small Block V8 and need a reliable head gasket, this Cometic Multi-Layer Steel (MLS) gasket is a solid option. It's specifically designed for aftermarket heads with a 12-23 degree valve angle and features a 4.200 inch bore. The compressed operating thickness is 0.080 inches, providing a precise seal for your engine build.

This gasket is built with multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in demanding sealing environments. This construction means the gasket can handle the shearing forces between aluminum heads and cast iron blocks, and it doesn't require any additional sealants for installation. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.080 inch on this particular gasket. It also features undersized water ports, allowing for customization during installation on aftermarket heads.

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 for high-output engines.
