Cometic Buick 3800 Series II/III V6 .030in MLS Cylinder Head Gasket - 3.840in Bore - RHS

If you're rebuilding the top end of your Buick 3800 Series II or III V6 engine, getting the right head gasket is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is specifically made for that job, featuring a 3.840-inch bore and a compressed thickness of .030 inches. It's designed for the right side of the engine.

Cometic builds these MLS gaskets with multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and works well with both aluminum and cast iron blocks. Because they're made this way, these gaskets don't need any extra sealants, making installation more straightforward. The center layer is also stainless steel, and Cometic uses different thicknesses for this layer to meet various engine requirements.

This gasket fits a wide range of GM vehicles from the mid-90s to the early 2000s, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro. Make sure to check the fitment details to confirm it's the right one for your specific application.
