Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.09 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 coating of Viton rubber. When compressed, it measures 0.036 inches thick, providing a solid seal for your Buick V6 engine. These gaskets are designed to handle the demands of high-output engines and work well with both aluminum and cast iron blocks, resisting the shearing forces that can occur between different metal types.

The stainless steel layers give this gasket increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a heat-resistant material capable of withstanding temperatures up to 482 degrees Fahrenheit (250 C), making it suitable for harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet different requirements. This gasket requires no additional sealants, simplifying the installation process.

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. It's a well-built option for rebuilding or repairing your engine's top end.
