Product Details
If you're rebuilding the top end of your Cadillac L37 or LD8 Northstar V8, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice. It's specifically made to fit a 94mm bore and comes in a .030 inch undersize, which is important if you've had the block or heads machined. This gasket is designed for the left-hand side (LHS) of the engine.
Cometic builds these gaskets with 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 conditions and various surface finishes without needing any extra sealants. This construction makes them ideal for sealing between aluminum heads and either aluminum or cast iron blocks, as they can manage the different expansion rates of these materials.
This gasket is a popular option for many vehicles, including models like the Cadillac DeVille, Seville, and Buick Lucerne. It's well-built to handle the demands of high-output engines.
