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.

Keep your Milwaukee-Eight engine sealed tight with this Cometic intake and exhaust manifold gasket kit. This 10-pack is ideal for shops and riders who perform regular maintenance or own multiple bikes. Each gasket features a durable Viton O-ring seal for dependable performance.

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.
