If it leaks out immediately then you should be able to determine the source of the leak with a visual inspection. Most common are the coolant hoses and the radiator itself.
The head gasket is internal and would not show any external signs of leakege.
Don't try to force the engine after an overheat condition since it could cause more damage such as a cracked engine block, unless you already have that problem.
