Cometic Mazda Miata BP Motor 1.8L DOHC 84mm .060in MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. The Viton coating is heat resistant up to 482°F (250°C), making it suitable for harsh sealing environments and various surface finishes. This gasket has a compressed operating thickness of .036 inches and is designed for an 84mm bore, specifically sized at .060 inches thick to accommodate engine rebuilds where a bit more clearance is needed.

MLS head gaskets are a solid choice for high-output engines because their multiple stainless steel layers provide increased strength and resistance to corrosion. They also offer the ability to rebound, which helps maintain a seal under stress. This design works well for mating aluminum heads to either aluminum blocks or cast iron blocks, as it can handle the shearing forces that can occur between dissimilar metals. Because they are a well-built, multi-layer design, these gaskets typically do not require any additional sealants for installation.
