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.

Ensure maximum sealing integrity for your Twin Cooled V-twin engine with this Cometic Multi-Layer Steel (MLS) head gasket. Sized at 4.060" bore with a .036" thickness, it's engineered to handle the demands of high-performance builds.

Why riders pick this

  • Multi-Layer Steel (MLS) construction for extreme durability
  • 4.060" bore diameter for big bore applications
  • 0.036" thickness for optimal compression
  • Designed for Twin Cooled V-twin engine configurations
  • Resists blow-out under high combustion pressures
  • Comes in a 2-pack for V-twin engine service

When pushing the limits of your V-twin, every component matters, especially the head gasket. Cometic MLS gaskets are a proven solution for maintaining a tight seal under extreme combustion pressures and temperatures, critical for modified or high-output engines.

  • 4.060" bore diameter for big bore applications
  • 0.036" MLS (multi-layer steel) construction for durability

Critical for Modified and Rebuilt Engines

Whether you're assembling a fresh big-bore motor or simply replacing gaskets during a top-end service, this Cometic MLS head gasket provides the confidence you need. Its robust construction is ideal for Harley-Davidson and Indian Motorcycle V-twins, particularly those with Twin Cooled heads and larger bores. Always verify your engine's bore size and cooling system configuration before ordering to ensure a perfect fit.

Common questions

What does MLS construction mean for my engine?

MLS (Multi-Layer Steel) gaskets use multiple steel layers to provide a stronger, more consistent seal that better withstands high combustion pressures and thermal cycling compared to traditional gaskets.

How many gaskets are included in this package?

This product contains two head gaskets, which is the correct quantity to service both cylinders of a V-twin engine.
