Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 3.875" bore diameter for precise fitment on Twin Cam engines
  • .066" compressed gasket thickness
  • Heavy-duty design engineered for high-compression and performance builds
  • Complete kit includes head gaskets and necessary sealing components

Cometic MLS head gaskets utilize multiple layers of stainless steel with precision-engineered embossments to provide maximum sealing around combustion chambers, oil passages, and coolant ports. The active sealing layers distribute pressure evenly while accommodating minor surface imperfections and engine movement. This gasket kit is ideal for engine rebuilds, performance upgrades, or replacement of worn OEM gaskets on Harley-Davidson Twin Cam motors.
