For those 1948 Packards with solid lifters Packard's specifications call for adjusting the lifters with the engine hot; 0.007" for intake and 0.010" for exhaust. With a fresh rebuild you'll want to give them an approximate adjustment and then do the final adjustment hot after the engine is installed and running. For a cold adjustment, adding about 0.003" to the hot clearances should be adequate.
