I have seen a lot of B and A blocks running cracked, with no welding. Since it is wet sleeves, the main worry is strength, not sealing.

Can you post a pic of the cracked area? I welded a jeep 134 f head between the two center cylinders. It cracked across the head bold threads. I drilled a small hole at the end of each crack and then I ground it out with a cutting disc on my 4 " grinder into the water jacket and welded it up solid using Certainum cast iron arc rod. Then i decked the block in a milling machine and drilled and rethreaded the hole. Luckily the crack didn't make it to the cylinders.
I found out later they used the jeep as a yard vechicle for plowing snow and ran it over heated a lot.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
