I think your 0.015" for exhaust is a bit too much, I didn't check Packard's specifications but Motors says 0.007" intake and 0.010" exhaust, hot and running. Doing them hot and running isn't exactly a fun job, but isn't all that bad and I really recommend you try it before you give up on it. Others may have better advice what correction to add if you must do them cold, but these valves have fairly short stems compared to the older senior engines, I'd think in the range of .003" additional at the most.
