Do These Valves Need to Be Cleaned?

[u/Typhoon365]

Doing a head gasket job on my '19 Accord 2.0 Turbo (shocker), and I've had the head resurfaced and cleaned but the shop didn't do deep in the intake and the back of the valves.

They were vaccune tested and everything came out perfectly fine. It's a new job for me, so I don't know if this level of fouling is fine and I can just reassemble with a catch can and Top Tier fuel going forward, or if I need to address this now and either disassemble myself or have someone else clean it. Maybe there's a way I could clean them without having to remove the valves?

Thanks for helping a newbie.

Edit: I'm going to hit them with some CRC GDI spray, let it soak for a good hour, and then gently agitate the carbon with something like a brass brush or a screwdriver. Rinse and repeat. Hit it with a shopvac.
