Cometic Chevy BB Gen IV 451 H/G 4.320 inch Bore .098 inch MLS Head Gasket

When you're rebuilding the top end of your Chevy Big Block Gen IV engine, you'll want to make sure you've got the right sealing components. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output engines. It features multiple embossed layers of stainless steel, with the outer layers coated in Viton rubber, a material known for its heat resistance up to 482°F (250°C). This construction means the gasket requires no additional sealants and is designed to provide maximum sealing performance.

The MLS design offers increased strength and resistance to corrosion, and it's well-suited for applications using both aluminum and cast iron blocks. The center shim layer is stainless steel, and its thickness can be varied to meet different requirements, with this specific gasket having a compressed operating thickness of 0.098 inches and a bore size of 4.320 inches. This gasket fits a range of Chevrolet and GMC trucks and vans from the early to mid-1990s, including models like the Chevrolet C1500 and GMC C2500 Suburban.
