Cometic 75-87 Buick V6 196/231/252 Stage I & II 3.86 inch Bore .120 inch MLS Head Gasket

The outer layers of this Cometic head gasket are coated with Viton, a heat-resistant rubber material rated up to 482°F, which helps ensure a solid seal in demanding conditions. This gasket is built with multiple layers of stainless steel, giving it increased strength and resistance to corrosion. The compressed operating thickness is 0.120 inches, and it's designed to work with both aluminum and cast iron blocks, handling the stresses between different metals effectively.

Cometic's Multi-Layer Steel (MLS) head gaskets are a popular choice for high-output engines because they offer maximum sealing performance without needing additional sealants. The layered stainless steel construction not only adds strength but also allows the gasket to rebound and resist corrosion, making it a well-built option for rebuilding or upgrading your engine. This gasket fits a wide range of Buick V6 engines from the mid-70s through the early 2000s, as well as various Chevrolet and Cadillac models from similar eras, making it a versatile part for many projects.
