Out of interest is that something you have actually seen or is it just second hand information from someone else?
As I and others have said it's just a 205 block picked for the bore tolerances, can't see how this would mean it would have more material in there?
Re the 202 block it's just a late Pinto block and yes plenty of people have used without problems, all internals should fit although I haven't done this personally.
