Cometic Oldsmobile Gen-2 Rocket V8 .051in MLS Cylinder Head Gasket - 4.270in Bore

If you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's designed with a 4.270-inch bore and a compressed thickness of 0.051 inches, making it suitable for a wide range of applications, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile vehicles from the 1970s and early 80s.

This gasket is built from multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This construction means the gasket seals well without needing any extra sealants, and it's designed to handle the demands of high-output engines, whether you're pairing aluminum heads with an aluminum block or a cast-iron block.
