I have never seen one do that before,
It appears the top surface has not been ground as you can still see the diamond stamping marks.
I would check the roundness of the bores ajacent to the cracks.
It should be possible to grind the cracks out enough to fill with JB Weld which will keep it running for a short while. ( the crack might well go a long way down the bore under the cylinder liners )
If all the studs will come out it will be worth having a go at a repair then get the top surface skimmed just enough to make it flat. fit all the studs back in with blue loctite which will hold then and stop leaks coming up the studs.
The above is a bodge fix which will get you running till you can find another block to build up preferably a non sleeved block.
if you can find another block easily then do not waste time on this block.
