If you are a few days from starting work, not much to do at this point. If it is going to be a while longer, pull all the spark plugs, disable the ignition, disconnect power to the fuel pump or disconnect the suction side hose, spray a some WD-40 or similar into the cylinders and crank. Yes, it will make a mess. But it will get most of the coolant out of the cylinders. Lastly, squirt some non detergent 30w into the cylinders and crank some more. You want to coat the cylinder walls with a good coat of fresh oil.

I would replace the gaskets on both sides. If one blew, the other might not be far behind. Unless there is a lot of rust damage, replace the gaskets and run it. Even if it burns a little oil, it would take many gallons of oil to equal the machining cost if you pulled the motor and had it reworked.
