Cometic 75-87 Buick V6 196/231/252 Stage I & II 3.86 inch Bore .036 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. The compressed operating thickness comes in at 0.036 inches, making it a solid choice for sealing your Buick V6 engine. MLS gaskets are known for their ability to handle high output engines without needing extra sealants, and they work well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The stainless steel construction gives them increased strength and resistance to corrosion, while the Viton coating on the outer layers is heat resistant up to 482°F (250°C), designed to handle tough sealing conditions and various surface finishes.

The center layer of this gasket is uncoated stainless steel, which can be varied to achieve different thickness requirements, like the 0.036 inch compressed thickness found here. This design helps them withstand the shearing forces that can occur between different metal types. 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 various Chevrolet applications such as the Camaro and Monte Carlo.
