Cometic Chevrolet Gen-3 Inline 6 .070in MLS Cylinder Head Gasket - 4.125in Bore

When you're rebuilding the top end of your Chevrolet Gen-3 Inline 6 engine, a good head gasket is crucial for sealing combustion pressure and coolant. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of higher output engines, offering a reliable seal without needing extra sealants.

This gasket features multiple layers of stainless steel for increased strength and rebound resistance, which helps it maintain a seal even with dissimilar block and head materials like aluminum heads on cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and a 4.125-inch bore, making it suitable for specific engine builds, including those using World Products Man-o-War blocks.

This gasket fits a wide range of classic Chevrolet, Buick, and Checker vehicles from the 1960s through the 1980s, ensuring you can find the right fit for your project.
