Exhaust valves cleaning

How do you clean this s*** of exhaust valves?

I've tried leaving them overnight in carb cleaner and nothing.
Wire wheel also doesn't work.
Only thing that would work that I can think of is putting them into drill
and sanding them, but than would probably damage valves.

And the best way. Replace them with larger (2.00/1.56) necked, cut-back swirl-polished SS performance valves and have the seats ground (with 3-5 angle valve job) to fit the new valves.

You could take a wire wheel to them, if SS, they should survive.

It's not for my vette, it's for cosworth 2.0 turbo engine and valves are
expensive and hard to find, at least from what owner says.

Hi Sliding !
do you have the "Chillit Bang" cleaner in Croatia?
Use it.... fill a glass with the needed amount to cover the valve. let it sit overnight. then repeat the next night.
valves will become as new!
