Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.02 inch Bore .066 inch MLS-5 Head Gasket

This product includes one Cometic Multi-Layer Steel (MLS) head gasket, designed for Buick V6 engines with a 4.02 inch bore. The gasket has a compressed thickness of 0.066 inches and is built to handle the demands of higher output engines without needing additional sealants.

Cometic constructs these MLS head gaskets from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction is ideal for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is uncoated stainless steel, allowing for adjustments in gasket thickness to meet specific needs.

This gasket fits a wide range of Buick V6 engines from the mid-70s through the early 2000s, as well as certain Chevrolet and Cadillac models. It's a solid option when rebuilding or repairing your engine's top end.
