Cometic Chevrolet Mark-IV GM Gen-V/VI Big Block V8 .030in MLS Exhaust Manifold Gasket Set

When you're rebuilding the exhaust system on your Chevrolet Mark-IV, GM Gen-V/VI Big Block V8, getting the manifold gaskets right is key to sealing in power and keeping exhaust fumes out of the cabin. These Cometic Multi-Layer Steel (MLS) gaskets are built to handle the high pressures these big engines can generate.

Cometic's MLS design uses multiple layers of steel to maintain a solid seal, even under extreme cylinder pressures. They're made to resist corrosion and won't burn through or get pushed out like some other gasket types can. Because they're designed to seal well on their own, you won't need any extra sealants, which makes installation cleaner. This set is specifically sized at .030 inches and features a 1.920 inch round port opening, fitting a wide range of Chevrolet, GMC, and other GM vehicles from the mid-60s through the early 2000s.
