The block looks to be lined and the two radial cracks look to go down behind the liners so, probably, not too much of a problem in themselves. A far bigger problem, though, is the pitting to the block face. Yes, you could remedy that by re-facing the block but the pitting looks quite deep in places so a fair bit of the face would have to be removed. Given that the top of the block isn't overly thick to start off with that might prove to be an excessive amount notwithstanding that doing so would have the potential to fatally weaken the already weakened area around the cracks. I'm afraid I'd be looking for a better block.
