Cometic Oldsmobile Gen-2 Rocket V8 .056in MLS Cylinder Head Gasket - 4.270in Bore

When you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, getting the cylinder head gaskets sealed up right is crucial. This Cometic Multi-Layer Steel (MLS) gasket is designed to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and block without needing extra sealants.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to 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 stainless steel, and its thickness can be adjusted to meet different requirements, with this specific gasket set to a compressed operating thickness of .056 inches and a bore size of 4.270 inches. These MLS gaskets work well with both aluminum-to-aluminum and aluminum-to-cast iron block combinations, as they can manage the shearing forces that arise between different metals.

This gasket fits a wide range of vehicles from the late 60s through the early 80s, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models. It's a well-built option for anyone looking to ensure a reliable seal for their V8 engine rebuild.
