Blast cabinets easiest most likely. Old school,,,,a dremel..

^ what he said.
Take it completely apart and take the core to shop. inspect valve seats to ensure they are good and not mushroomed flat. if they are replace valves and get valve job. at a minimum lap the new valves in.

have fun with it.

Bead blast it with glass bead.
It will come out perfect & not hurt anything.

If you don't have access to a bead blaster, I used Suzuki Combustion Chamber cleaner to clean up heads for years. It is EXTREMELY caustic, and routinely ate thru thick rubber gloves. Think oven cleaner caustic. It would soften up the hard carbon deposits enough that they would come off with a stiff toothbrush.
