Cometic Chevy Mark-IV Big Block V8 .039in Fiber Intake Mani Gasket Set

This is the Cometic C5428-039 intake manifold gasket set, specifically made for Chevrolet Mark-IV Big Block V8 engines. It's a .039 inch thick fiber gasket designed to create a reliable seal between your intake manifold and cylinder heads. This set is built using AFM material, which is a chemically blown, compounded nitrile synthetic rubber bonded to an aluminum core. This construction offers good temperature resistance, over 250°F, and maintains strong torque retention.

The AFM material is known for its 85 percent recovery rate, meaning it can compress and seal effectively without needing additional sealers or a re-torque after installation. This makes the installation process more straightforward. These gaskets are manufactured to meet and exceed OEM quality standards, ensuring they perform well in a variety of applications, including those using Brodix Race-Rite heads like the 26 Degree, Dragon Slayer, BB-1, BB-2, BB-2 Plus, BB-2 X, and BB-2 Xtra models.

This gasket set fits a wide range of Chevrolet vehicles from the mid-60s through the early 90s, including popular models like the Impala, C10 Pickup, and Camaro. It's a well-built option for anyone rebuilding or working on their Mark-IV Big Block V8 engine.
