About Cometic

Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.

Ensure a robust seal for your Milwaukee-Eight intake and exhaust manifolds with this Cometic O-ring gasket 10-pack. Engineered to OEM specifications, these gaskets provide dependable sealing under the high-temperature and high-pressure conditions of your Harley-Davidson M8 engine.

Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.
