Cometic Oldsmobile Gen-2 Rocket V8 .030in MLS Cylinder Head Gasket - 4.270in Bore

When you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, getting a reliable seal between the cylinder head and the block is critical. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of performance engines, offering a strong seal 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 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 in thickness; this particular gasket has a compressed operating thickness of 0.036 inches and is designed for a 4.270-inch bore, with a 0.030-inch oversize to account for block machining. It's well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as it can manage the stresses between different metals.

This gasket fits a wide range of vehicles from the mid-70s to early 80s, including models like the Buick LeSabre, Chevrolet Impala, and Oldsmobile Delta 88. Make sure to check the fitment data to confirm compatibility with your specific vehicle.
