Below is what I used when I bolted my dual plane M1 intake on. It shows 2 steps (72 in/lbs and 12 ft/lbs), but it also said to torque certain bolts in 5 steps. Center 4 bolts in order to 72 in/lbs, then the outer 8 bolts in order to 72 in/lbs, then all bolts in order to 12 ft/lbs followed with an additional check to make sure they are all still at 12 ft/lbs.
Yes, that is basically the same as the 2000 FSM I have.
In short, start all bolts. Tighten the 4 center bolts to 12in. lbs. and keep going back in 12in. lb increases, until 72in. lbs are reached (on the 4 center bolts)
Tighten the 8 remaining bolts to 72in lbs.
Tighten all to 12 ft. lbs.
Thanks for your post.
