Zimmy,
Change the
oil immediately and then maybe if you still have the head off put a light amount of
oil around the top of the piston with it down and turn the car over. That way you will spread a little
oil over the cylinder wall and take away any chance of water or
antifreeze causing a ring to stick. I really don't think if you got everything out immediately you have anything to worry about. Just turn the motor over a few times before starting it.
