Is this block junk?
Worth even taking to get looked at?
I've used worse,
Magnaflux the block to make sure it's not junk, as for the squirters , worry about later, you can braze the hole, I had one come to me last year where the squinter holes were filled in with...Wait for it......Flex seal...Yeap Flex seal.......30k miles on that flex sealed block...that guy should use that in the commercial.
I've used a few blocks where a Squirter hole has seen the big end off a rod, for those I drill out main main feed & tube it . At point I can open the oil holes I want to keep...and the squirters get blocked off.
