I have heard it said that later heads were modified to make them less prone to cracking. I don't know any more.

The aluminium alloy used to cast the 1.9TD heads is a different (somewhat stronger) grade. I believe the material used for the exhaust valves is an upgrade too. (both from the 1.9D engines and the 1.7TD)
Dimensionally, they are indeed identical. (except the camshaft output drive that is)
