Cometic Buick Big Block V8 .027in MLS Cylinder Head Gasket - 4.312in 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 Buick Big Block V8 engines and features a 4.312-inch bore with a compressed thickness of .027 inches. This gasket is built to handle the demands of higher output engines, ensuring a solid seal between your cylinder heads and engine block.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This Viton coating is tough enough for various sealing environments and surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block setups. The center layer is uncoated stainless steel, allowing for precise thickness control.

This gasket fits a range of Buick vehicles from the late 60s through the mid-70s, including models like the Electra, LeSabre, and Riviera. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation. Just make sure to refer to your vehicle's service manual for the correct installation procedure.
