Removal of the cylinder head would be only neccarsary if there is excessive pressure build up in the system and overheating.
eg: the coolant is constantly spilling from the expansion tank.
if the system is completely filled and warmed up there is always a bit of water comming out due to the expansion of the water.
i dont know the condition of the external piping or heat exchanger but this one also needs to be drained.
otherwise you will have old cooling water remaining in the system, specially a tube cooler is a nice part where deposits settle.

shortly after overhaul you can get black coloured or rust coloured water.
there is a lot of assembly grease in the system.
usually we run it on plain water first to see if we dont have any leaks.
then use a coolant system cleaner, drain everywhere you can.
exhaust manifold, side covers etc.
then fill with deminireralised water and nalcool 2000 or Cat SCA.
its always best to use demin water, because this doesnt create kettle stone on the liners and block.
