Description

  • Black Shovelhead Heads – VELOCITY version of the OEM Bore Billet Aluminum (6061-T6) Heads/Intake system for the Harley-Davidson™ Shovelhead models.
  • Black Anodized (Heat and UV-resistant coating).
  • Bolt-on installation for all ’66-’84 72CUI or 80CUI models, designed to match OEM-shaped pistons (not supplied) – including all available overbore sizes.
  • 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 custom pistons, valves, guides, fasteners, etc. to worry about.
  • Fast, very efficient ports designed to make peak power/torque within the useful RPM range. 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, super-fast design of the combustion chamber yields 10.35:1 calculated compression ratio with OEM-shaped pistons (@ 80CUI). Works well on the hi-octane (e.g. North American 94) pump gas. Compression releases included for easy starting.
  • Valvetrain (AV&V and KPMI) components accept up to .625” valve lift, with almost .200” lift before valve-to-valve contact. Using tall camshafts may require an additional machining to provide necessary clearances.
  • Increased cooling area drops the head’s operating temperature up to 35F.
  • Single (Y-Split) CNC Billet Aluminum Intake Manifold (seals included) interfaces with Super E style carb, etc. We have completely redesigned the Intake <–> Head interface via proper EVO seals to eliminate vacuum leaks.
  • Exhaust interface accepts both OEM single-bolt flanges as well as the aftermarket three-bolt pattern.
  • Hi-tensile steel thread inserts (headbolts, intake, exhaust) installed; all original thread sizes, no need for “special” fasteners.
  • OEM oil drain location.
  • ***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 )
