Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load--resulting in less bore distortion. The stainless steel outer layers utilizing FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Q:

Are these left and right specific? I bought one thinking it was a set and it appears to work only on the driver side. It says front on the gasket and it would have to be upside down to work on pass side.

These head gaskets are great, blown other brands, but these are the best. Only advice i can offer, is make sure you get your thickness correct before you order, as this can make it an expensive excersize if you have to re-order again.

I love the Multi layer gaskets so much! No need to worry about blown head gaskets or coolant leaks. If you ever need to remove the heads it is a much easier to clean as well. Peace of mind
