The tips are the worst part. From what I can see, there is some wear but probably not too far from normal for an engine with some miles. I'd clean them up to see how much is carbon. It's actually never a bad idea to disassemble the whole thing and clean it up with a gun cleaning kit.

I'd say the shaft wear is not bad and the rocker arm bores show some wear but it doesn't look bad enough to worry about yet, in my opinion. 

Personally, I don't think much noise would come from that assembly based on what I'm seeing. It's not perfect, but few used engines are.
