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.

The Cometic Milwaukee-Eight EST gasket kit provides every seal, gasket, and O-ring needed for a complete engine overhaul, specifically tailored for cam changes. This comprehensive kit ensures a reliable and leak-free assembly for your high-performance Milwaukee-Eight V-twin.

Why riders pick this

  • All seals, gaskets, and O-rings for a full engine overhaul
  • Includes MLS head gaskets for superior sealing
  • Steel Viton-coated base gaskets for durability
  • Blue Viton valve stem seals for heat resistance
  • AFM material components for robust sealing

When performing a cam swap or major engine service on your Milwaukee-Eight, having a complete and reliable gasket kit is essential. This Cometic EST kit takes the guesswork out of sourcing individual components, providing everything you need in one package. Engineered with advanced materials, these gaskets are designed to withstand the demands of modified M8 engines.

  • Steel Viton-coated base gaskets ensure durability and prevent leaks

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.
