Cometic GM Gen-V/VI BB V8 .125in Fiber Intake Mani Gasket Set-1.750in x 2.500in Rect. Port

When you're rebuilding the top end of your big block Chevrolet Mark-IV or GM Gen-V/VI V8, getting a good seal on the intake manifold is crucial. This gasket set from Cometic is built to help you achieve that. It's designed for rectangular ports measuring 1.750 inches by 2.500 inches, and the gaskets themselves are 0.125 inches thick, providing a solid foundation for your intake setup.

These gaskets use Cometic's AFM material, which is a synthetic rubber bonded to an aluminum core. This construction offers good temperature resistance, over 250°F, and the material maintains its shape well with 85 percent recovery. A notable benefit of this material is that it doesn't require any gasket sealers, and you won't need to re-torque the manifold after installation, which can simplify your rebuild process. This set includes the main intake manifold gaskets as well as the end rail and distributor gaskets, so you have what you need for a complete seal.
