I tried answering your previos post but could not post - it's clearly OK now!(so answered it just now)
Beware of hydraulic lock when a head gasket goes - bent rods are expensive.
There are other reasons for water in the oil but as you have the head off you cannot pressurise the system easily to check a leaky sleeve seal.
You don't usually get more than one problem occurring simultaneously. Seems as if you know why there is water in the oil. Just slow to get the fault fixed.
