Cometic Chevrolet Mark-IV Big Block V8 .095in MLS Cylinder Head Gasket - 4.630in Bore

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 strong seal. This Cometic MLS (Multi-Layer Steel) head gasket is built to handle the demands of these powerful engines, offering a .095 inch thickness and a 4.630 inch bore to match your specific build.

Cometic uses a multi-layer steel construction for durability and a consistent seal, even under high compression and temperature. The outer layers are embossed and coated with Viton, a high-performance material known for its resistance to oil and heat, helping to prevent leaks and ensure longevity. This gasket is designed to fit a wide range of Chevrolet and GM vehicles from the mid-60s through the late 90s, including popular models like the Impala, C10 Pickup, and Camaro, making it a solid option for many big block projects.

When installing, always ensure your cylinder heads and block surfaces are clean and flat to achieve the best possible seal. This gasket is a key component for maintaining proper compression and preventing coolant and oil from mixing.
