If you did not make the mistake of pouring cold water into a hot engine after it has overheated or while it is still hot, and perhaps doing so several times, it is unlikely that you've cracked your head.

Inspect your head gasket for tears....remove your head carefully so as not to laterally damage the HG in the process.
