Can anyone point me to an existing thread about how to properly clean my Exhaust Valves?

Subject car: 2005 9-5 Aero (160,000 miles)

While I'm doing the head gasket I decided to refresh the Timing Chain, Guides and Gears, and replace the Valve Stem Seals. I have decided to clean the valves up which is easy for the Intake Valves but I have questions about the Exhaust Valves.

Questions: (for reference see pictures)
  • Is there a coating on the exhaust valves that I need to worry about?
  • It seems that there is a lot of buildup on the valves (unless its coated). Is this normal?
  • If this is a coated valve it seems that some of the coating is chipping off. Is this an issue?
  • Is it recommended to just replace them? I'd rather not given the cost.
Thanks to everyone for any help you can provide.
Cheers - Aaron

Btw I always take the head to a shop and have them go over the valves as seal and alignment is the real deal…
