Cometic Oldsmobile Gen-2 Rocket V8 .120in MLS Cylinder Head Gasket - 4.125in Bore

If you're working on an Oldsmobile Gen-2 Rocket V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.125-inch bore and a compressed thickness of .120 inches, making it suitable for a range of high-output applications. This gasket is engineered to provide maximum sealing performance, ensuring your engine runs smoothly and efficiently.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, resisting corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the .120-inch thickness on this particular gasket. These gaskets are ideal for use with aluminum heads on either aluminum or cast iron blocks, as they can withstand the shearing forces that can occur between different metals. Because they are MLS, they don't require any additional sealants, simplifying installation.

This gasket fits a wide variety of vehicles from the mid-60s to the mid-70s, including models like the Oldsmobile 98, Buick LeSabre, and Pontiac Grand LeMans. It's a solid option for rebuilding or upgrading your V8 engine.
