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.

This Cometic Twin Cam rocker box assembly gasket kit is engineered to provide a reliable seal for your V-twin's rocker box covers. Designed as an OEM-quality replacement, it effectively prevents oil weeping and leaks at the critical rocker box interface. Ensure your Twin Cam engine stays sealed tight with this essential component.

USPS damaged the gaskets

Came in USPS bent , I didn't use them and threw them in the trash after JP Cycle refunded me. I used my old ones and added gasket sealant to them.

packaging

The gaskets worked great, no more leaks, however the packaging could be better. The gaskets are metal and shipping them in an envelope makes for bent gaskets and crossed fingers hoping they won't leak.
