I bought a "Maintenance shop" O-320-A2B n/d. Had to have to whole thing checked out so I had the crankcase shop rework the engine mounts from Conical to Dynafocal 1.

Yes, but then you will have to rework the accessory housing, as plumbing for the oil pick up is drastically different between the two. Also, with the later configuration there may be issues with engine mount interference due to them being conical with a later style sump.
Good Luck,
