I have not seen a...
M110 block for a very long time, but if it is similar to the late M130 block, there were "slots" cut into the block between the cylinders; these slots were between the holes that allowed for coolant to pass from the water jacket in the block up into the head.
These slots [if present] were a problem, as due to the thin cylinder walls, there was very little "meat" for the head gasket to seal against.
The shop that I was affiliated with would fill the slot with an epoxy resin, trim the resin flush, and clean the water passage holes; this would allow the head gasket a little more contact area for a better seal.
Good luck with your problem,
