| CRF450R Head Porting – CT Racing has done significant amounts of flow bench and dyno testing to offer you the best port layout for your CRF450R / X. 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. | $350.00 |  |
| CRF450R 3 Angle Valve Job – Quality valve job. | $144.00 |  |
| CRF450R 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 |
|
| CF450R 5 Angle Radius Race Valve Job for +1mm 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. | $216.00 |  |
