Cometic Chevrolet ZL1 Mark-IV Big Block V8 .040in MLS Cylinder Head Gasket - 4.375in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your Chevrolet ZL1 Mark-IV Big Block V8. If you're rebuilding the top end of your engine, especially one that's built for more power, a solid head gasket is crucial for keeping everything sealed up tight. This gasket is designed with a compressed operating thickness of .040 inches and a 4.375-inch bore, making it a good fit for specific Camaro and Corvette applications from 1969 and 2012-2018 Camaros.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and different surface finishes, even when you're pairing aluminum heads with cast iron blocks. This design means you don't need to use any extra sealants; the gasket does the work on its own, providing maximum sealing performance for high-output engines.
