Cometic Chevrolet Gen-3 Inline 6 .036in MLS Cylinder Head Gasket - 4.125in Bore

Starting with a compressed operating thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. It's constructed from multiple layers of stainless steel, with the outer layers featuring a heat-resistant Viton rubber coating. This design is ideal for high-output engines and works well with both aluminum and cast iron blocks, resisting the shearing forces that can occur between different metals. The stainless steel construction also gives it increased strength and the ability to rebound, while also resisting corrosion.

The Viton coating on the outer layers can handle temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation. This gasket fits a wide range of classic Chevrolet, Buick, and Checker vehicles, offering a solid option for rebuilding or repairing your Gen-3 Inline 6 engine.
