Product Details

If you're rebuilding the top end of your Chevrolet Mark-IV Big Block V8, getting the cylinder head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures and heat of these powerful engines.

Cometic uses multiple layers of stainless steel for this gasket, which gives it strength and helps it resist corrosion. The outer layers are treated with a special Viton rubber coating on both sides. This coating is designed to handle tough sealing jobs and high temperatures, up to 482°F, making it a reliable choice for your engine build. The 4.630-inch bore size and .047-inch thickness are specific to certain Mark-IV Big Block configurations.

This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 90s, including models like the C10 Pickup, Impala, and Camaro. Always double-check your specific engine and bore size to ensure this is the correct gasket for your project.
