How bad are these valve tips?

I removed the valves from one of the heads on my busted 360, they all seem to have visible wear but how bad are they actually? They are from a set of factory Magnum heads I assume were reconditioned when I got them, I put about 25k miles on them with a Lunati Voodoo hydraulic (fast ramps) and factory 1.6 Magnum rockers. I'd like to reuse them for a street engine if possible, the seats are good and so are the guides. The individual ones are the worst I picked out from the set. If I did use these again I would probably run a slower-ramp cam.
