I think the 1.9 and 2.1 blocks are different internally too. The
2.1 has a longer stroke and has different pistons. The cylinders
may be the same but the head are different too.

Well, I am not an expert. If the blocks are the same people would
have been interchanging blocks.

Am I off the topic? This is a good subject. Thanks to both Mike and
Scott.
