Cometic Chevy Mark-IV GM Gen V/VI Big Block V8 Fiber Intake Manifold Gasket Set 1.754in x 2.505in

Cometic Gasket is known for making well-built sealing solutions for a wide range of vehicles. This intake manifold gasket set is designed for Chevrolet Mark-IV and GM Gen V/VI Big Block V8 engines. It helps ensure a proper seal between your intake manifold and cylinder heads, which is crucial for engine performance and preventing vacuum leaks.

The gaskets are made from AFM material, which is a chemically blown synthetic rubber bonded to an aluminum core. This material can handle temperatures over 250°F and has a strong torque retention, meaning it won't loosen up over time. Because of its properties, this gasket doesn't require any additional sealers and you won't need to re-torque it after installation. The material also offers 85 percent recovery, helping it maintain a solid seal even under demanding conditions.

This set fits a broad range of vehicles, including models like the Chevrolet Impala, C10 Pickup, and Corvette from various years. The rectangular ports measure 1.754 inches by 2.505 inches, designed to match the factory specifications for these Big Block engines.
