Cometic Chevy Small Block 4.165 inch Bore .030 inch MLS Head Gasket (w/All Steam Holes)

If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, getting the right head gasket is crucial for a strong seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, offering a reliable seal between your cylinder head and block without needing extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This gasket has a compressed operating thickness of .030 inches and a bore size of 4.165 inches, with all steam holes included to help manage heat. It's a solid option for pairing aluminum heads with either aluminum or cast iron blocks, as the MLS construction can manage the shearing forces that can occur between different metals.

This gasket fits a wide range of Chevrolet and GMC vehicles from the early 80s, including models like the C10, Camaro, and Caprice. Make sure to check the fitment details to confirm it's the right choice for your specific application.
