Product Details
This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Cadillac L37 and LD8 Northstar V8 engines. It features a 94mm bore and a compressed thickness of 0.075 inches, intended for the left-hand side (LHS) of the engine. MLS head gaskets are a popular choice for rebuilding or repairing engines that see higher output, as they offer a strong seal without needing additional sealants.
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 different surface finishes, making them suitable for joining aluminum heads to either aluminum or cast iron blocks. The center layer is stainless steel and can be varied in thickness to meet specific engine requirements, like this 0.075-inch version.
This gasket fits a range of GM vehicles, including models like the Cadillac DeVille, Eldorado, and Seville, as well as the Buick Lucerne and Pontiac Bonneville. It's a well-built component for ensuring a solid seal on your Northstar V8.
