It’s designed for Chevrolet Mark-IV Big Block V8 engines and features a 4.375-inch bore with a .023-inch thickness. This gasket is built to handle the tough sealing requirements of these powerful V8s, ensuring a solid seal between your cylinder head and engine block.

The outer layers are embossed and then coated on both sides with a Viton rubber material. This coating is heat resistant up to 482°F (250°C) and is formulated to handle a variety of harsh sealing environments, different load conditions, and various surface finishes you might find on an engine block or cylinder head. This multi-fit gasket is suitable for a wide range of Chevrolet vehicles, including models like the C10 Pickup, Impala, and Corvette from various years.
