Yep, you got a mess, but not necessarily a done motor. I looks like you still had lots of coolant left inside. Any left is always better than none.

Is there any coolant in the oil? If there is, it should be easy to tell. The oil will be green and gooey. Drop the pan and look around. Any metal in the oil?

Please post pics after you pull the heads; both of the cyls and valves/heads.
Place a metal straight edge on the cyl & head mating surfaces to see if they are warped. Let's see if they show any warping.

If it was caused by a head gasket failure, you may get away just a new gasket. Or maybe a quick shave of the mating surfaces.

Hope this helps.
Cheers,
