Cometic Chevy Gen-4 Big Block V8 .060in HTS Exhaust Manifold Gasket - 2.250in Round Port - 20 Pack

Starting with a .060 inch thickness, these Cometic HTS exhaust manifold gaskets are built to handle the heat and pressure common in Chevy Gen-4 Big Block V8 engines. They feature a 2.250 inch round port, designed to match up with many factory and aftermarket exhaust manifolds for a solid seal. This pack includes 20 gaskets, making it a practical choice for engine builders or shops working on multiple vehicles.

Cometic uses HTS (High Temperature Synthetic) material, which is known for its ability to withstand extreme temperatures and resist blow-out, helping to prevent exhaust leaks. This well-built construction ensures a reliable seal even under demanding operating conditions. The precise port sizing helps maintain exhaust flow efficiency, which is important for engine performance. These gaskets are a popular choice for rebuilding or repairing the exhaust system on a wide range of classic and some later model Chevrolet vehicles, including models like the C10 Pickup, Impala, and Camaro.

When installing, ensure both the manifold and cylinder head surfaces are clean and flat for the best possible seal. Having a full pack of 20 ensures you have spares or enough for multiple projects without needing to reorder.
