FWIW, I have opened up C-113/C-123 blocks for valve jobs that had similar damage, and were NOT leaking. I have also rolled the dice and put a new gasket on and have them leak. I know this one is for an F-12/F-14, but the concept is the same. I know this is a VERY common damage area on these.
Remember, the sleeves take most of the combustion stress from a block perspective, but not all. Also, the stress in that area of these blocks are vertical because of the head bolt torque......very little lateral stress there. The head gasket seals the top of the sleeves and potentially can seal the cracked area also. these are low RPM, low compression engines, so worries about block integrity becomes an exercise in liquid retention (oil or coolant or both) depending upon where the failure is.
no more are being made. 5 years from now, there will be even less of these blocks..............
Once it goes to the scrap yard, there is no turning back. I am not suggesting a course of action either way, but rather I am giving you some perspective and things to think about. The beautiful thing here is that there is no "right" or "wrong" answer. If your block serial number matches your tag, and that is important to you, repair it. If that sort of thing doesn't bother you, then get a new block. Is this going to be a show tractor, or are you going to work the snot out of it? You have to decide what is important to you and what your pocket book will bear as far as costs........
