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.

For riders pushing the limits of their Twin Cam engines, a robust head gasket is essential. These Cometic head gaskets are built to modern standards, offering reliable sealing under high stress. With a .030" thickness and sold in a 2-pack, they're ready for your next performance build or refresh.

Why riders pick this

  • Reliable sealing for high-performance Twin Cam engines
  • Engineered with modern gasket technology
  • Precise .030 inch thickness
  • Two gaskets included for a complete top-end job

These Cometic head gaskets are precision-engineered for Harley-Davidson Twin Cam engines, offering a critical seal for your V-twin's top end. Designed to modern gasket technology standards, they provide reliable sealing even in demanding, high-performance applications where engine integrity is paramount. The .030 inch thickness is a common choice for builders looking to fine-tune compression and valve clearance, making them a go-to for performance Twin Cam builds.

Optimized for Twin Cam Performance

  • Engineered for precise fitment on Twin Cam engines
  • Advanced gasket technology for reliable sealing under pressure
  • .030 inch thickness, ideal for specific engine build requirements
  • Supplied as a 2-pack, covering both cylinders of your V-twin

Critical for Engine Integrity

The head gasket is a small but vital component in any engine, especially when dealing with the power and heat generated by a performance Twin Cam. Using a high-quality gasket like this Cometic offering helps prevent leaks and maintains consistent compression, both crucial for horsepower and longevity. Always ensure your cylinder heads and barrels are meticulously prepared before installation to achieve the best possible seal.
