Different valve stem diameters?

I am looking for information relating to valve stem diameters on K-Series engines, particularly the 16V cylinder heads (might be all of the K-series engines?).



I have unfortunately lost my electronic copy of the MGTF manual as a result of a virus on my PC.



In short, are all the valve stem diameters on the 16V heads identical or not. I am not concerned about valve head size or amount of undercut - looking at stem diameters at the interface with the valve stem seal specifically.
