Cometic Porsche 928 83-97 100mm Bore .040 inch MLS Head Gasket Left Side H/G

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.040 inches and a 100mm bore, specifically for the left side of your Porsche 928. MLS gaskets are a smart choice for high-output engines because they offer excellent sealing without needing any additional sealants, making them ideal for mating aluminum heads to either aluminum or cast iron blocks. They can handle the stress that comes from dissimilar metals working together.

The strength of these gaskets comes from their multiple stainless steel layers, which also help them resist corrosion and maintain their shape. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating is designed to perform well in tough conditions and on various surface finishes. The center layer is plain stainless steel, and its thickness can be adjusted to meet different requirements, like the 0.040 inch thickness found in this specific gasket.
