Cometic Chevy Small Block 4.165 inch Bore .056 inch MLS-5 Head Gasket (w/All Steam Holes)

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, this Cometic MLS head gasket is a solid choice. It's built with a multi-layer steel design, which gives it increased strength and the ability to resist corrosion. This gasket is designed to provide maximum sealing performance, especially for engines that are running higher output levels. It's suitable for use with both aluminum and cast iron blocks, and it can handle the shearing forces that can occur between different metal types.

The compressed operating thickness of this gasket is 0.056 inches, and it features a 4.165-inch bore. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This Viton coating is designed to meet the demands of tough sealing environments and varying surface finishes. The center layer is uncoated stainless steel, allowing for flexibility in thickness requirements. This gasket is designed to work without needing additional sealants.

This gasket is designed to fit a wide range of Chevrolet and GMC V8 applications from the early 1980s, including popular models like the C10, Camaro, and Corvette. Make sure to check the full fitment list to confirm compatibility with your specific vehicle.
