Looks like that head ate a valve/s and some rocker arms... I'd smooth all the rough edges in the combustion chamber out so you don't have any hot spots. You should be ok, but make sure you get it shimmed correctly otherwise, you could be facing a similar fate.

hmm, i'm thinking about going with mazworx "87mm combustion chamber" to remove all that ugly marks/dents in that chamber.

and for the head, i was thinking the same thing with you, it seems like 2 rocker arms broke and slapped to the bottom.

Definitely don't run it like that. Those sharp edges can cause hot spots and detonation, or can act as stress risers and lead to cracks.

Somebody definitely over revved that thing.
