What Head / Valve service 04 CRF 250x

I know this is hot topic but im still new. I have a 04 CRF 250x mostly trail riding. I picked up this bike for a good deal few years back, and the maintenance is unknown on it. It runs good as far as I can tell but I did notice the valves are begging to walk about. I have never done any real work on it other than valve adjustment and oil changes. I see other people are putting 07 and 08 R heads on them. How does this compare to stock? I also fear it time for new piston and possibly a Jug. Should I stay with stock or size up. Or am I just putting lipstick on a pig? This will also be my first top end job performed by me and my son as are attempting to learn together. so feel free to over elaborate.
