no. if you just blow all the coolant out of your cylinders with a air gun or by another means you will be fine. Another good idea is to use a sanding block and sand paper and sand the deck (top of the block) and bottom of your head to get rid of all the eccess gasket so you get a flush clamping force on your new gasket. The coolant in the oil wont be a problem if you change your oil before startup, after the job. But if there was a lot of oil in your coolant then chances are there is biuld up in your system. You cant flush it without a machine but you can drain it and fill a few times with water to try and flush it out. By the way if you didnt already know, the way to bleed out the air in your coolant once you finish your job is to turn on your heater, make sure the ac is off, and let it run with the raidator cap off untill the heater blows hot air and the coolant at your radiator cap no longer has bubbles or goes down. This will insure that there isnt an air pocket in the system, possibly overheating the engine and forcing you to repeat the job.
But the thing about head gaskets is that they dont usually just blow, that isnt why it overheated. Usually the engine overheated for some reason and then it blows. So make sure your fixing the problem along with the head gasket. good luck.

well if the thermostat was stuck open then there would be plenty of flow and no overheating. The only purpose of a thermostat is so the engine can heat up faster. Retaining the coolant in the engine untill it reaches a certain temp, then opens. But if it is open then you would just take a long time to heat up in the mornings but it wouldnt cause a problem. But always change the thermostat when doing a head gasket. If i were you id check the waterpump make sure its intack. if it is then your fine to through it back together. New thermostat, raidator, and if the water pump is fine then thats about it.
