do yourself a favor and don't run only water in your radiator. the coolant is called antifreeze for a reason, it doesn't freeze  . it the water in your cooling system freezes, more than likely it will also be in your engine, and you will then be screwed b\c your engine and radiator would be f'ed up.
if you don't know what the heads are, please don't try to fix the car. but if u actually do, then take them off, set a straight edge on it, and see if you can slide a really thin feeler guage under the straight edge at any point. if you can, its warped.
oh, and welcome
