Yes, the stage one hot cam is a good one.  It can be installed without any mod's to the piston although the clearances should be checked.  I also use WebCams torque grind.  They come as a set and both cams should be changed,

The difference between the ti valves and the SS valves is a slight drop in top end rpm.  For an Intermediate rider he would never know the difference.  Also, setting the bike up for torque instead of top end will make it much easier to ride and allows for better traction on shorter tracks.

If the bike is ridden hard, the springs will lose their tension before the valves go bad.  I usually check the springs with a spring tester and replace them if they test low.  Have never had a problem with any broken springs or retainers with the Kibblewhite setup.  The guides in these engines seem to last for a long time.  Since the cam pushes directly down on the valve cups, it keeps the valve from rocking in the guide like they do in a rocker arm type of engine.  Therefore, there is less wear stress on the guides.

Of course, all of this stuff should be checked at regular intervals when he re-rings the bike.
