Cometic Chevy Small Block 4.165 inch Bore .060 inch MLS-5 Head Gasket (w/All Steam Holes)

Cometic Gasket is a well-known name for creating robust sealing solutions, especially for engines that need to perform. This particular head gasket is built for Chevrolet Gen-1 Small Block V8 engines and is designed with a 4.165-inch bore and a compressed thickness of 0.060 inches. It's a Multi-Layer Steel (MLS) gasket, which means it's constructed from several layers of stainless steel for increased strength and the ability to rebound, helping it resist corrosion and handle the stresses of high-output engines. This gasket fits a wide range of vehicles, including models like the Chevrolet C10, Camaro, and GMC C1500 from the 1980s.

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 is important because it helps the gasket seal effectively even under demanding conditions and on various surface finishes, whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The center layer is also stainless steel, allowing for precise thickness control. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
