Cometic Chevy Small Block 4.200 inch Bore .098 inch MLS-5 Head Gasket (w/All Steam Holes)

Starting with a compressed thickness of 0.098 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for the demands of high-output Chevy Gen-1 Small Block V8 engines. It features multiple layers of stainless steel for strength and rebound, with the outer layers coated in heat-resistant Viton rubber. This construction means it seals effectively without needing additional sealants, making it suitable for combinations of aluminum and cast iron blocks and heads.

The MLS design inherently offers increased strength and resistance to corrosion, while the Viton coating is rated for temperatures up to 482 degrees Fahrenheit, handling harsh sealing environments and varying load conditions. This gasket includes all steam holes, which are important for managing heat and pressure within the engine. It's designed to fit a wide range of vehicles, including models like the Chevrolet C10, Camaro, and GMC C1500 from the early to mid-1980s.
