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.
When embarking on a full engine overhaul or rebuild for your Harley Twin Cam, the Cometic Complete EST Gasket Kit is your all-in-one solution. This comprehensive kit provides every gasket and seal needed to refresh your entire engine. It's designed to replace all worn factory gaskets, ensuring a complete and reliable seal across the entire V-twin platform.

Each part is manufactured to factory-spec materials and tolerances, ensuring a precise fit and reliable, leak-free performance. It's the ideal choice for riders and shops looking for a thorough and professional rebuild.

Common questions
What gaskets are included in this complete kit?
This kit includes a complete set of gaskets and seals for all engine locations on a Twin Cam, covering heads, cylinders, covers, and all other seals required for a full engine rebuild.
Will this kit fit my Milwaukee-Eight engine?
No, this specific kit is designed exclusively for Twin Cam engines. Milwaukee-Eight (M8) engines utilize different gasket specifications and require a different Cometic part number. Please use our Shop by Bike tool to ensure proper fitment.
Do I need any other parts for an engine rebuild with this kit?
This kit provides all the necessary gaskets and seals. Depending on the scope of your rebuild, you may still need internal engine components such as bearings, piston rings, or valves, which are not included in this gasket kit.

A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
