Cometic Chevy Mark-IV GM Gen V/VI Big Block V8 .125in Fiber Intake Manifold Gasket Set

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 applications. It’s a .125 inch thick fiber gasket set that helps ensure a solid seal between your intake manifold and cylinder heads, which is crucial for proper engine performance and preventing vacuum leaks.

The material used here is AFM, a chemically blown synthetic rubber bonded to an aluminum core. This construction offers good heat resistance, rated for over 250°F, and it has a notable 85 percent recovery rate. This means the gasket can compress to seal effectively and maintain that seal under torque, even as temperatures fluctuate. A practical benefit of this material is that it doesn't 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, C10 Pickup, and Camaro from various years. The ports are rectangular, measuring approximately 1.750 inches by 2.500 inches, designed to match common intake manifold configurations for these big block V8s.
