Hopefully a couple of photos will appear with this posting?
I'm not sure if it helps, but the first photo shows a motor I bought that had been assembled using a silicone sealant. I thought that I had undone all the stud but couldn't separate the block from the crankcase.
I blamed the sealant and used mineral turps to soften it. Finally, I discovered the stud in the valve chamber.
This is a 3 bearing motor converted to two bearing.
The second photo shows the cleaned crankcase with extra studs for a new block and the centre bearing stud situation. I don't know if this helps at all?
