Cometic Chevrolet Mark-IV GM Gen-V/VI Big Block V8 .060in HTS Exhaust Manifold Gasket Set

Built with three to five layers of stainless steel, these Cometic HTS exhaust manifold gaskets are designed to handle the heat and pressure of your Mark-IV, Gen-V, or Gen-VI Big Block V8. The stainless steel construction offers increased strength and resists corrosion, while the outer layers are embossed and coated with Viton rubber. This Viton coating can handle temperatures up to 482°F and is designed to seal effectively even on less-than-perfect surfaces, making them a solid option for a wide range of Chevrolet and GM vehicles from the mid-60s through the mid-90s, including models like the C10 Pickup, Camaro, and Impala.

The multi-layer steel (MLS) design, combined with the Viton coating, helps these gaskets rebound and maintain a strong seal under various conditions. This means you can expect a more reliable seal for your exhaust manifolds, helping to prevent leaks and maintain proper engine performance. The .060 inch thickness is a specific measurement that accounts for the machining of your engine block or heads, ensuring a proper fit and seal when rebuilding or repairing your exhaust system.
