| RZR 800 Head Porting – CT Racing has done significant amounts of flow bench and dyno testing with the Polaris RZR 800 to offer you the best port layout for your application. We highly recommend getting a valve job at the same time the head is being ported. Our CNC valve job ties in with the port work to offer extremely effective flow numbers. We have found the 800 really runs well with oversize valves, so if your planning on porting budget oversize +1mm valves. | $450.00 | |
| RZR 800 3 Angle Valve Job – Quality valve job. | $152.00 | |
| RZR 800 5 Angle Radius Race Valve Job – The 5 angle radius Race valve job significantly raises the flow characteristics at low valve lift and definitely shows a horsepower increase throughout the useable power curve. | $192.00 | |
| RZR 800 5 Angle Radius Race Valve Job for +1mm Intake & Exhaust Valves – The 5 angle radius Race valve job significantly raises the flow characteristics at low valve lift and definitely shows a horsepower increase throughout the useable power curve. The 5 angle valve job really shines on big valves as the seat diameter is opened up all the way into the aluminum casting, blending to the port work. Adding +1mm valves to a modified engine package helps the mid to top-end horsepower. Most aftermarket hi compression pistons are clearanced for +1mm valves. | $240.00 | |
