Never had a problem installing Egge or Kanter new guides, I just drove them in with the same driver I used to remove the old ones. But I do pack them in the freezer (or better yet, dry ice) for a time to make installation easier. Hopefully you've carefully measured the depth to which the old guides were installed before you removed them and compared the old and new guides as there was a running change during 1938 for the 115 guides. By all means see the information in the shop manual - there is about a 1/4" difference in the depth to which the revised guides are seated, and they are shorter.

No Packard did not use hardened valve seat inserts, though it's possible they were installed in your car at some point in the past.
