When you're rebuilding the top end of your Chevy Mark IV Big Block V8, getting a good seal on the intake manifold is crucial. This gasket set from Cometic is made with AFM material, which is a synthetic rubber bonded to an aluminum core. It's designed to handle temperatures over 250°F and maintains its seal even with strong torque retention, meaning you won't have to worry about re-torquing after installation.

The material has an 85 percent recovery rate, which helps it conform to the mating surfaces for a leak-free fit. These gaskets are a direct replacement for your stock ones, fitting rectangular ports that measure 1.754 inches by 2.505 inches and are .047 inches thick. They are manufactured to meet and exceed OEM quality standards, giving you peace of mind that they'll perform reliably.

This gasket set is designed to fit a wide range of Chevrolet and GM vehicles from the 1960s through the 1990s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup. You can install them without needing any additional gasket sealers, making the job a bit more straightforward.
