Cometic 75-87 Buick V6 196/231/252 Stage I & II 3.86 inch Bore .030 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 2000s, like a Regal, LeSabre, or even a Camaro from the 90s, this gasket is designed to seal your cylinder head to the block effectively. It's built with multiple layers of stainless steel, which gives it strength and helps it resist corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs without needing any extra sealants.

The multi-layer design is key here; it allows the gasket to rebound and maintain a strong seal even with different materials like aluminum heads on cast iron blocks. This gasket has a compressed thickness of 0.030 inches, which is important for maintaining proper compression ratios. The Viton coating on the embossed outer layers is rated for high temperatures, up to 482 degrees Fahrenheit, making it suitable for engines that see a lot of work.
