Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.02 inch Bore .045 inch MLS Head Gasket

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a Buick V6 engine from the mid-70s to the late 80s, like a Regal or LeSabre, this gasket is designed to provide a strong seal for your cylinder heads. It's built to handle the demands of higher output engines, ensuring your engine runs smoothly and reliably.

This gasket uses multiple layers of stainless steel, which gives it increased strength and helps 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 coating is crucial for sealing effectively against different engine block and head materials, whether you have aluminum heads on an aluminum block or aluminum heads on a cast iron block. The compressed thickness is set at .045 inches, providing a precise fit for engines with a 4.02-inch bore. Because it's an MLS gasket, it doesn't require any additional sealants, making the installation process more straightforward.
