Most has already been covered, one thing not mentioned, the cylinder sleeves just sit down in the block, held down by the head. You must not turn the engine or disturb the liners in any way. If any ride up,the seal will be broken and coolant will leak under the liners into the crankcase. To replace the liner orings is a major job. The pistons will have to come out, the sealing surface thoroughly cleaned. You can bolt the liners down with a short head bolt and washers to prevent them from coming up.
The block cracking was more a problem with the earlier Z engines. By the late 50 it was not as bad, but still worth a look while you are in there. Look at the webs between the cylinders.
Were there obvious head problems? Like overheating, steam out the exhaust, mystery coolant loss, loss of power/misfire? Those are typical blown head gasket symptoms.
Coolant in the oil is also a symptom, but the cylinder orings or a cracked block can also cause coolant in the oil, typically without the other symptoms.
One other concern, how long ago was it parked? If it has sat with water in the engine for more than a few months, it may have stuck rings. If the engine is stuck best get it loose before removing the head. Any time an engine sticks there is always a possibility the rings will be damaged or soon fail.
Once it is back together the head bolts will need to be retorqued and the valves adjusted once up to temperature. A temporary fuel supply will be necessary to allow it to run without the tank in place.
Service manuals are cheap and readily available. It will more than pay for itself in mistakes not made!

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
