I would not be doing that at all, the only way to wash a head with water based product is bare head ONLY. You will find that in the real world your idea is heavily flawed. You cannot use minimal liquids as any soap on earth will corrode aluminum if left to dry up, why you have to flood the cleaned area once worked over. The popular engine cleaners like simple green and purple power never are found where I work on engines, they have ruined way too many parts.
I use fuel now because of the only good quality ethanol in it has, it allows the fuel to wash clean off with no afterfilm like straight gas leaves behind because the ethanol component mixes with water. I will kill as well to avoid at all costs trying to ever clean assembled parts, you are asking for problems when the cleaning medium does not 100% disappear, and valves in place as an action is begging to seize valves up once you run the engine.
Myself, if I were stuck with your issue the entire head would have to be disassembled to clean it right. Meaning all parts marked to go back in the right places. The slightest speck of hard detritus in a cam bearing and scar it up and head is then junk. Heads with that much mechanical complication inside them need to be treated just as if you were working on a human body and have cut inside to do the work. Meaning it cannot be too clean, meaning second after that any pre-lubing like oiled valves guides will be gone and very possible alien substances in oil galleries.
Having said all that, yours and do as you will................
