What kind of dimensions are you looking for? The service manuals have most everything you will need.

All the bores are the same, almost. There are a few 46ci blocks that are larger bore but they are rare. The strokes are different, there are 3 different ones, 40ci, 42ci, and 46ci. The piston pin height is all the same, the difference is made up in rod length. The 40ci has a closed chambered head (small cc) the 42ci is a little bigger and the 46ci is the biggest.

I'd say if you have the skills to machine a new set of heads,you probably should have the skills to do some measuring on the engine their going on.
