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 you're wrenching on a Twin Cam, reliable sealing is non-negotiable, especially in performance applications. These Cometic head gaskets are engineered to provide that critical seal. Sold in a convenient 2-pack, they ensure you have the right components for a solid top-end assembly.
Why riders pick this
- Reliable sealing for Twin Cam V-twin engines
- Engineered with modern gasket technology
- Two gaskets included for both cylinders
- Ideal for performance engine builds
These Cometic head gaskets are designed specifically for Harley-Davidson Twin Cam engines, providing a crucial seal between the cylinder head and barrel. Manufactured using modern gasket technology, they're built to withstand the demands of high-performance V-twin builds, ensuring integrity under extreme heat and compression. Whether you're doing a routine refresh or a full performance build, don't overlook the foundation of a good seal.
Engineered for Performance
- Precision-engineered for a reliable seal on Twin Cam V-twin engines

The Right Foundation for Your Build
Choosing the correct head gasket thickness is vital for maintaining proper compression and valve clearance. This .040" thickness is a common choice for many Twin Cam setups, balancing performance and reliability. Always confirm the required thickness for your specific engine build to ensure optimal results and prevent future headaches. Pair these with fresh hardware for the best possible seal.
