Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.02 inch Bore .051 inch MLS Head Gasket

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built to handle the demands of higher-output engines, offering a reliable seal without needing extra sealants. This gasket is a good choice whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block, as it can handle the different expansion rates between those materials.

The construction 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 tough sealing conditions and various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements – in this case, it's set at a compressed operating thickness of 0.051 inches. This design helps it rebound and resist shearing forces, making it a durable option for your engine rebuild.

This gasket fits a wide range of Buick V6 engines from the mid-70s through the early 2000s, including models like the Buick Regal and LeSabre, as well as many Chevrolet applications. It's designed for a 4.02-inch bore, making it suitable for Stage I and Stage II performance levels.
