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 Evolution Sportster's primary sealed tight with this Cometic primary gasket and seal kit. Engineered to prevent leaks under demanding conditions, this kit ensures your V-twin performs reliably without unexpected drips.

DONT FOLLOW PRINTED INSTRUCTIONS!

DON’T FOLLOW THE INSTRUCTIONS ON THE BOX!!! It says recommended torque is 42 lb/ft. You know what happened at 32lb/ft? One of bolts broke! And I was lucky there was long enough piece sticking out to remove it without drilling out! Check photos.
