If you bough a car whose overheating is due to a fan, a thermostat, plugged radiator, even a water pump, then you are lucky.
But if the overheating is due to a blown head gasket, cracked block, then god bless you.
How difficult it is to do a head gasket? Is there a way to know if it is a blown head gasket, or a cracked block, before you pull the head?
