Cometic Buick Big Block V8 .030in 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 0.030 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and engine block.

What makes this gasket stand out is its construction. It’s made from multiple layers of stainless steel, which gives it increased 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. This makes it suitable for use with both aluminum and cast iron blocks, and it doesn't require any additional sealants for installation, simplifying the process.

This gasket fits a range of Buick vehicles from the late 60s through the mid-70s, including models like the Electra, LeSabre, and Riviera. It's a solid option if you're rebuilding or working on the top end of your Buick V8.
