You'll need custom rods. The blocks are not the same. The D23 block has a deck height increase of 11mm over the D20. I have no idea about the D25 I4, but the bore change could indicate different bore spacing as well as deck height increases. There's no way to know without making measurements, and I don't think anyone has done that to date.
Ford is not like GM who builds multiple displacements from the same block. Ford will change all the dimensions, but keep the same basic design.
