Cometic Head Gasket - .030" Twin Cam 2-Pack - Harley Twin Cam
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 building a Twin Cam, attention to detail is key, and that includes your head gaskets. Cometic delivers factory-engineered gaskets designed for reliable sealing under all conditions. This 2-pack of .030" thick gaskets provides the essential components for a secure top-end assembly on your V-twin.
