Twin Cam Heads: Speed And Science® newly re-designed “FEROCITY Rev. 2.0” Billet Aluminum (6061-T6) Heads for the Harley-Davidson™ Twin Cam models.

  • This is a fully assembled, bolt-on set, suitable for up to 110CUI models with flat-top pistons.
  • Set for up to .650″ valve lift.
  • This system achieves very strong torque curve and very respectable HP that peaks exactly where needed.
  • Our product is user-friendly and easy to service down the road also. No special-order pistons, valves, guides, fasteners, etc. to worry about.
  • Re-designed (Rev. 2.0) fast, very efficient ports produce even better power/torque. This headset responses well to different cams and fuel maps. Your bike will pull hard from the get-go all the way up to the redline. The longevity and fuel mileage won’t suffer either.
  • Proprietary design of the super-fast 85CCM combustion chamber. Hi-octane (e.g. North American 94) pump gas recommended along with the proper tuning.
  • Includes M12x1.25 threaded holes for automatic compression releases.
  • ***The difference in surface finish between the Intake (coarser) and Exhaust (smoother) ports is intentional.
  • Warranty details and conditions are listed in the Installation Manuals ( Manuals download page )
