The torque spec is 25 Nm, there is no specific sequence. I snug them all finger tight and then alternate top and bottom from cylinder to cylinder starting in the center and working outwards. Sort of, 3 top, 4 bottom, 2 bottom, 5 top , 1 top, 6 bottom etc, get then all pretty tight and the put the torque wrench on them for the last turn again starting in the center and alternating You basically want it tightened down to spec as evenly as possible.

got intake back on ,hopefully remembered where all things attach and had no bolts left over,only lost one clip to cc actuator rod,but i improvised till i get a new one.feels good to have tackled that job,not so hard,but i took my time and had good tools-that really helps.now i need injectors rebuilt-have to save money and send to c sean watts.intake was definitely lined with gunk ,but did not seem to have any serious restriction-decided to put it back on for now without getting it cleaned out.
