It would definitely require that the cylinders have identical height. So light machining of the highest cylinder may be required. And checking of squish and combustion chamber volume is a good idea in any case. Any machining of the heads will require a larger lathe, and possibly a more rigid fixture than just a mandrel. And a lathe large enough to swing a one piece head. Alternatively a CNC mill or a mill with a rotary table can be used, of course.
I have seen in previous threads that it has been recommended to cut Daytona heads in two.

There are several versions of the 1-piece "Daytona type" head.
2V0 is USA 1979 RD400F (unique combustion chamber and thicker 1-pc gasket)
3J7 is Canada 1979-80 RD400F & RD400G and Australia/Oceania 1979-80 RD400F & RD400G
