Product Details
If you're rebuilding the top end of your Chevrolet Mark-IV or GM Gen V/VI Big Block V8, getting the intake manifold sealed up right is crucial. This gasket set from Cometic is made from Aramid fiber, a material known for handling high temperatures and resisting creep, meaning it won't compress over time and require a re-torque. This is a big help during assembly, letting you focus on getting everything else buttoned up.
The Aramid fiber material is also fuel resistant and asbestos-free, so you don't need to worry about additional sealants or harmful substances. These gaskets are designed with a rectangular port measuring 1.750 inches by 2.500 inches, which is a common size for many big block applications. They are precisely .060 inches thick, ensuring a proper fit and seal when you're putting your intake manifold back on.
This gasket set fits a wide range of classic Chevrolet and GM vehicles, from the 1965 Bel Air to the 1980 C10 Suburban. Cometic has been a trusted name in gaskets for a long time, and this set is a solid option for your rebuild.
