Cometic Oldsmobile Gen-2 Rocket V8 .120in MLS Cylinder Head Gasket - 4.200in Bore

If you're working on an Oldsmobile Gen-2 Rocket V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for ensuring a strong seal. It's designed with a 4.200-inch bore and a compressed thickness of .120 inches, making it suitable for a wide range of applications, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 80s.

What makes this gasket stand out is its construction. It's built from multiple layers of stainless steel, which gives it 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 varying surface finishes without needing additional sealants. This robust design is ideal for pairing aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.

This gasket is a well-built component designed for high-output engines. Its multi-layer steel construction provides the rebound and strength needed for reliable performance, and the Viton coating ensures it meets the demands of various sealing conditions.
