Cometic Buick 3800 Series II/III V6 .070in MLS Cylinder Head Gasket - 3.840in Bore - RHS

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed outer layers coated in Viton, a heat-resistant rubber material rated up to 482°F. It features a compressed operating thickness of .098 inches and a bore size of 3.840 inches, specifically designed for Buick 3800 Series II and III V6 engines. This gasket is engineered to provide maximum sealing performance for high-output applications, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.

The MLS construction uses multiple layers of stainless steel, which not only increases strength and resistance to corrosion but also allows the gasket to rebound effectively. This design helps withstand the shearing forces that can occur between different block and head materials. Because of its advanced construction, this gasket does not require any additional sealants, simplifying the installation process. The center shim layer is stainless steel and can be varied to achieve different thickness requirements, with this particular gasket set to .070 inches before compression.

This gasket is a solid option for a wide range of vehicles, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro from the mid-90s to early 2000s. Its robust design ensures reliable sealing under demanding conditions.
