Cometic Chevy Mark-IV Big Block V8 .039in Fiber Intake Mani Gasket Set-1.754in x 2.505in Rec. Port

Cometic Gasket is known for making well-built sealing solutions for a wide range of engines. This intake manifold gasket set is designed for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines, helping to ensure a solid seal between your intake manifold and cylinder heads. It's a crucial part for maintaining proper air-fuel mixture and preventing vacuum leaks.

This gasket set uses Cometic's AFM material, which is a compounded nitrile synthetic rubber bonded to an aluminum core. It's rated for temperatures over 250°F and offers 85 percent recovery with strong torque retention, meaning it stays sealed under pressure and heat. A notable benefit of this material is that it does not require gasket sealers or re-torquing after installation, simplifying the job.

This gasket set fits a broad range of vehicles, including models like the Chevrolet Impala, Camaro, and C10 Pickup from various years. The ports measure 1.754 inches by 2.505 inches, fitting rectangular port heads. This is a direct replacement part designed to meet or exceed OEM quality.
