People have succesfully done this. But I would not expect n/a head to last as long as Turbo head. Turbo head has reinforced water passages and thicker deck to withstand higher thermal stresses of Turbocharging.
Maybe adding a intercooler is a good idea. I'm in same situation as you - I'm going to fit an intercooler with or without Turbo cylinder head.

And Turbo-Prechambers are 1mm bigger in diameter and have bigger internal volume. If you are going to fit turbo prechambers, the hole in the head needs reaming out to size. it's 14mm n/a, 15mm Turbo.

I have one OM 603 turbo engine with cracked head.Can i put NA head on this engine becouse i cant find any turbo head.Only NA heads
Hello, mirza26
So did you installed NA head?
I`m in same situation.
Found good deal for NA head.
But still thinking, not sure for 100%
Someone tells its ok, someone tells it will not work because of cooling.
