Cometic Chevrolet Mark-IV Big Block V8 .092in MLS Cylinder Head Gasket - 4.540in Bore

If you're working on a Chevrolet Mark-IV Big Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing your cylinders. It's built with a compressed thickness of .092 inches and a 4.540-inch bore, designed to handle the demands of these powerful engines. This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 90s, including popular models like the Impala, Chevelle, and C10 pickups.

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, meaning you won't need additional sealants. The center layer is also stainless steel, providing a robust foundation. This construction is ideal whether you're pairing aluminum heads with an aluminum block or an iron block, as it helps manage the shearing forces between different metals.

This gasket is a well-built component for rebuilding or repairing your Mark-IV Big Block. Ensure you have the correct bore size and thickness for your specific application.
