No, but....

If he warped the head all bets are off, and he
probably needs a new head and head gasket.  If it was
only 1 mile, he may be fine as far as the head goes.
The blown head gasket may have caused the hose failure
if it was weak by over-pressurizing the system.
Either way, it sounds like that head is coming off.
Does the oil have water in it?  It will be nice and
foamy if it does, then you know for sure it's the head
gasket.  Based on what you say though, I will assure
you it's blown, even without checking the oil.  Does
mysteriously loose coolant?

HTH,
