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 undertaking a full engine overhaul on your Evo Big Twin, a comprehensive gasket kit is indispensable. This Cometic Evo Big Twin EST Gasket Kit supplies every gasket, seal, washer, and O-ring required to fully rebuild your V-twin engine. It's engineered with modern materials to ensure reliable sealing and sustained performance.

Installed a new Baker 6spd OD on my 85th Anniversary FLHTC so I replaced the chrome covers and their associated gaskets, all look fabulous tomorrow I'll ride to Illinois and put down about 470 miles to break in the new gears and I'll also find out if all the covers and gaskets on my new tranny top and end covers are sealed and working well. But I'm pleased with how they fit and look.
