12v and 24v block?
No, there are some major differences between them. I don't remember exactly what they were, but I remember lots of discussions on VWVortex when the new motor came out.
Some coolant passages are different, the stud holes for the head are in different locations, other than that I think the blocks are the same. Bore size should still be the same, as well as deck height.

will the pistons work?
