This redesigned Vortex II cylinder head casting eliminates the limitations of the original Vortex cylinder head casting. The previous version, in Pro Stock form, used 47mm intake and 39mm exhaust valves. After it was CNC ported to optimize airflow, it flowed 160cfm. The Vortex II uses 46mm intake and 38mm exhaust valves, and flows as much air without porting. You read it right – it flows 160cfm with guides and a valve job with the ports AS CAST! Getting more air flow from smaller valves means smaller valve pockets in your pistons which will give you more compression and a more efficient combustion chamber.

Vortex II Cylinder Head features:

  • High strength 356-T6 aluminum casting.
  • Redesigned semi-downdraft ports flow enough air as cast to support 300hp.
  • No porting required – no welding or thin spots.
  • O-ringed valve cover (included in Top End Package).
  • Machined for high lift 3 bolt cams with improved thrust flanges.
  • No bearing inserts required for Kawasaki.
  • Dual 10mm spark plugs.
  • Full radius combustion chamber.
  • 26 degree valve angle allows longer guides, and more retainer to seal clearance.
  • Captured cam follower design for less side loading, and longer follower and bore life.
  • Increased gasket surface for improved seal.
  • More material around stud holes for increased strength.
  • Capable 270+hp w/500 lift cams (more w/pro stock style cams).
  • Capable of running all season w/minimal maintenance.
  • Our customers have run 7.50’s with this package.
  • Contains many of the same engine components as pro stock top end.
  • Can be updated at a later date to pro stock engine.
  • Fully machine & assembled — just needs piston deck height set and cams degreed.
  • Perfect combination for nitrous (nitrous piston kit available at no extra cost!).
