Best procedure lugs into hub/rotor

Got two mint KH SBP hubs and a set of mid 90’s new USA made rotors to assemble with new lugs (Dorman 610-130). Not sure of best procedure to do this. Should I use a press to push them in one at a time through both components simultaneously or use a hammer and punch? Already got new races in and don’t want to screw up these parts. As always, advice and suggestions greatly appreciated. Thanks.
