Cometic Chevy Small Block 4.200 inch Bore .092 inch MLS-5 Head Gasket (w/All Steam Holes)

If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, a solid head gasket is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built for high-output engines, offering a reliable seal without needing extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance, which also allows the gasket to rebound and maintain its seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This gasket has a compressed thickness of 0.092 inches and is designed for a 4.200-inch bore, with all steam holes included to help manage heat. It's a good choice for engines using aluminum heads with either aluminum or cast iron blocks, as the MLS construction can handle the different expansion rates between these materials.

This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks. Make sure to check the fitment details to confirm it's the right gasket for your specific application.
