Cometic Chevrolet Mark-IV GM Gen-V/VI Big Block V8 .042in MLS Exhaust Manifold Gasket Set

If you're working on a Chevrolet Mark-IV or GM Gen-V/VI Big Block V8 engine, these Cometic exhaust manifold gaskets are what you need to seal up your exhaust system. They are specifically designed for these large displacement V8s, helping to ensure a leak-free seal between your exhaust manifolds and cylinder heads. This is important for maintaining proper engine performance and keeping exhaust fumes contained.

These gaskets are made with Multi-Layer Steel (MLS) construction, which is known for its durability and ability to handle high temperatures. They can withstand temperatures up to 2000°F, making them suitable for even the most demanding applications. A notable feature is their ability to compress and seal even on surfaces that aren't perfectly flat, which can save you time and hassle during installation. Because they seal so well on their own, they require no additional sealants, simplifying the job.

This gasket set fits a wide range of Chevrolet and GM vehicles from the mid-60s through the mid-90s, including popular models like the Chevrolet C10 Pickup, Impala, and Corvette. Make sure to check the full fitment list to confirm compatibility with your specific vehicle.
