by "usual order i meant 5,6,3,8,4,7,2,9,1,10 type thing, as for getting to the 90 ft lb i usually do them all to 30, then check them all at 30 twice more as the first couple you tighten will now be loose,
once they are all at 30 then i move on to 60ftlb and check again,
then finally do them all to 90 and check,
the 4 outer bolts i use "used" standard head bolts and they are tightened as part of the sequence to the same torques
