Cometic Mercedes-Benz 6.0L M120 6.9/7.0L M297 90mm Bore .070in MLS Cylinder Head Gasket - RHS

This Cometic Multi-Layer Steel (MLS) head gasket starts with a .070 inch thickness and a 90mm bore, designed to seal the combustion chamber effectively in high-output engines. It's built with multiple layers of stainless steel, which gives it strength and resistance to corrosion, while also allowing it to rebound and maintain a seal even with the stresses between different block and head materials, like aluminum to cast iron. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal under demanding conditions without needing extra sealants.

This gasket is a well-built option for a range of vehicles, including models like the Mercedes-Benz 600SEL, CL600, and SL600, as well as the Mitsubishi Lancer. The Multi-Layer Steel construction provides increased strength and the ability to withstand the shearing forces that can occur when mating dissimilar metals, making it a reliable choice for rebuilding or repairing the top end of these engines. The compressed operating thickness is a precise 0.036 inches, ensuring it fits within the engine's original specifications.
