You can tell the old tappets and rollers from the new ones by the side play of the roller pin. In the old ones the roller pin had keepers to keep the pin in the roller. The new DLC ones free float and have no keepers to keep the pin centered. You can push them in and out freely.

Appreciate the response. The build date on mine is 2/16 so I'd be out for the newer style for sure. Just a little more info to store in the arsenal. I may go ahead and order the kit to rebuild the pump and get it done before I hit the 300k mark. After hearing all the horror stories, it's just not feasible to gamble with my livelihood.
