This year I did the valves as well.
At a minimum you'll want to change your cam chain with that piston.
Spray brake clean in the ports and see if any leaks out the valves. Tell you wether you need to go in there anyways.

From what I've heard they're not that expensive, but could cost you a whole heap if they fail.
I had my old 426 rebuilt after losing 5th gear and didn't replace the tensioner when the motor was torn down.
The bike ran fine for a 1000ks or so then dropped three inlet valves and took out many other things...
