head torque on 420

What torquing method is best? I have read about two methods. One is to torque both heads to 30nm ,after 30min go to 60nm. The other method it to torque to 30nm,60nm 30min. then back off each bolt 1/4 turn and go back to 60nm [in proper order]. Also what method should i use to clean out head bolt threads?
