Narrative:

Reviewed pre departure clearance at las and noted 'cleared as filed las MEAD8....' did not notice the 'turn right heading 060 degree line' which is 4 lines removed from the routine block. Took off on runway 1R and flew departure as published. Passing 4000 ft, turned toward bld. An alert departure controller noted our turn and corrected us back to a 060 degree heading. No conflicts existed. Suggest that a 'cleared as filed' routing be amended only by voice, ie, 'cleared for takeoff, turn right heading 060 degrees for vectors to the mead 8 departure.' if an exception to the clearance must be issued on the pre departure clearance, it should be in the 'routine' grouping.
