Cometic Oldsmobile Gen-2 Rocket V8 4.2 inch Bore .030 inch MLS Head Gasket

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for the Oldsmobile Gen-2 Rocket V8 engine with a 4.2-inch bore and a compressed thickness of .030 inches. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block.

This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the .030 inches specified for this particular gasket. Because it's an MLS design, it doesn't require any additional sealants and works well with both aluminum-to-aluminum and aluminum-to-cast iron setups, as it can manage the shearing forces between different metals.

This gasket fits a wide range of vehicles, including models like the Buick Skylark, Chevrolet Camaro, and Oldsmobile Cutlass. It's a well-built component designed for a direct fit on the specified engines.
