    You should purchase Chiltons book about your truck at parts store, the procedure is in that book, tightening them in sequence like you said will cause problems with pushrods and lifters and maybe rockers. You start with engine at TDC on #1 at compression position and next go round is done after turning crank one full turn so #1 is at exhaust position. You also will adjust different lifters/pushrods with each position. Or have qualified tech do it.
