I have a massive HP upgrade for rhino 700 owners for sale here. This is a Racers Edge CNC ported head with 2mm oversized intake and exhaust valves. The chamber was also done at the time of the CNC porting and the head surface is perfect. High rpm springs and retainers were also added. All valves/ guides and seats are flawless. This head has less than 10 hrs on it. This head will pull strong to 9000 plus rpm.
