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 it's time for a full engine overhaul on your Twin Cam, this Cometic EST gasket kit delivers everything you need for a complete, leak-free rebuild. This comprehensive kit includes MLS head gaskets, steel Viton-coated base gaskets, blue Viton valve stem seals, and AFM material components, ensuring every critical seal is replaced with high-quality parts.

This kit is comprehensive, providing all gaskets, seals, washers, and o-rings necessary for a complete engine overhaul. This includes MLS head gaskets, steel Viton-coated base gaskets, blue Viton valve stem seals, and AFM material components.
Will this EST gasket kit fit my specific Harley-Davidson model?
Cometic EST Gasket Kits are designed for Harley-Davidson V-twin engines. It's important to confirm that your specific engine model is a Twin Cam EST to ensure perfect compatibility.
Can I purchase individual gaskets from Cometic instead of the full 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?
