Cometic Oldsmobile Gen-2 Rocket V8 .027in MLS Cylinder Head Gasket - 4.270in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for Oldsmobile Gen-2 Rocket V8 engines, featuring a 4.270-inch bore and a compressed thickness of 0.027 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in tough sealing environments. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses. Because it's an MLS design, it doesn't require any additional sealants and works effectively with both aluminum and cast iron blocks, even when paired with aluminum heads, as it can manage the shearing forces between different metals.

This head gasket fits a wide range of vehicles, including models like the Buick Skylark, Chevrolet Camaro, and Oldsmobile Cutlass. It's a solid option for rebuilding or repairing your engine, providing a reliable seal for your Gen-2 Rocket V8.
