Cometic Chevy BB 4.545in Bore .060 inch MLS 396/402/427/454 Head Gasket

Cometic Gasket has a solid reputation for making well-built engine sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for Chevrolet Big Block V8 engines, specifically those with a 4.540-inch bore and designed to be installed at a compressed thickness of 0.060 inches. This gasket is a great choice for rebuilding or repairing your engine, offering reliable sealing for high-output applications.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel for increased strength and resistance to corrosion, which helps it rebound and maintain a seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for use with both aluminum and cast iron blocks. This design means you don't need any extra sealants for installation.

This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the mid-80s, including popular models like the C10 Pickup, Impala, and Camaro. It's a solid option for anyone working on a classic Chevy Big Block build.
