Ktm 530 using oil

My 09 530 with 140hrs started using 2 to 3oz every 2 to 3 hrs of hard riding. I decided it was time for rings and valve stem seals. The only thing found on tear down was some buildup on piston under intake valves, the seals on these seemed a little loose. Would this be an indication that my intake seals where infact leaking? This is my first time this far into a motor, so bear with me.

Heres what the intake valves looked like.

What's the best method for cleaning the valves and head. I'm guessing I need to stay away from anything abrasive. Do I need to do anything special when installing my new rings a far as oiling rings and cylinder wall. I'm also looking for break-in advice, I've read a little about the Motoman procedure. Thanks for your help
