Cometic Chevrolet Gen-1 Small Block V8 4.200in Bore .040in MLS Cylinder Head Gasket w/ Steam Holes

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice. It's built to handle the demands of higher output engines and fits a wide range of vehicles from the early 80s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps ensure a reliable seal even with different head and block materials, like aluminum heads on cast iron blocks, and it means you won't need any extra sealants during installation. The compressed operating thickness is .040 inches, and it includes steam holes to help manage heat.
