Cometic Chevy Gen1 Small Block V8 .066in MLS Cylinder Head Gasket - 4.080in Bore - Vortec Heads

When you're rebuilding the top end of your Chevy Gen 1 Small Block V8, you need a head gasket that can handle the job. This Cometic Multi-Layer Steel (MLS) head gasket is built for that purpose. It features a compressed thickness of .066 inches and is designed for a 4.080-inch bore, specifically intended for use with Vortec heads. This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion, while also allowing it to rebound effectively.

The outer layers of this gasket are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to meet the demands of harsh sealing environments and varying load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements. Because it's an MLS gasket, it requires no additional sealants and is ideal for sealing aluminum heads to either aluminum or cast iron blocks, effectively handling the shearing forces that can occur between different metals.

This gasket fits a wide range of Chevrolet and GMC vehicles from the early 1980s, including popular models like the Chevrolet C10 and GMC C1500 trucks, as well as the Chevrolet Camaro and Corvette. It's a well-built component designed for reliable sealing in performance applications.
