Cometic Chevrolet Gen-1 Small Block V8 4.165in Bore .027in MLS Cylinder Head Gasket

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It features a 4.165-inch bore and a compressed thickness of .027 inches, making it suitable for a wide range of classic American vehicles. These gaskets are built to handle the demands of higher output engines and are engineered to provide a strong seal without needing additional sealants.

The MLS construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This design is effective whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied in thickness to meet specific engine requirements.

This gasket also includes features like valve pocketed bores and steam holes, which are important for proper engine function and cooling. It's a well-built option for rebuilding or repairing your engine, offering a reliable seal for many Chevrolet, Buick, and GMC applications from the early 1980s.
