Also note that there are 2 plug depths. 16mm or 19.5mm. The new style valve needs the correct one or it will rattle inside the port and not seat. I looks like from the TSB that the dividing line was whether your motor was manufactured pre or post 2006. Just talked to Cummins and the parts guy read it the same way I did. My '09 motor has the 16mm plug.
Nilao is right. The plug is the large diameter one. #2 in the picture.
