Hi hondahotty,
If the head is cracked, resurfacing is not gong to work. The head has to be replaced.
All flushes available requires the engine to be running and most don't work too well. Engine and cooling system would have different types of flushing agents.
If oil and coolant have mixed and are all over the places, for the oil side, drain off whatever contaminants in the oil pan and and with aid of compressed air, try to get out as much as possible. Add some new oil into the oil pan and repeat above till oil is no more milky. A little coolant inn system is inevitable and would not do much harm as it would dry out after a little running.
If the interior of the engine is very dirty and contaminated with sludge, the head would be more noticeable, I would suggest removing the oil pan and oil pump strainer to clean.
As to cooling system, on the block side, use water to flush out the block and any other water passages. After assembly of engine, do not install thermostat first.
Run engine and flush out the oil contaminants with a hose. Add a little cleaning detergent, dishwashing liquid works well, to the cooling system and let engine tunn till it heats up and perform flushing again.
Repeat process until water in system looks clean. Reinstall thermostat and top up with water to test if system is clean and no leakages are present.
Run for a few days and if you do not have any problem, replace the water with coolant after flushing.
