6.5 intake manifold

[Van]

I know I should just buy a manual...but some easy information right now would help me a bunch!
What is the proper tightening sequence and torque spec for the 6.5 intake manifold?
Thanks

To keep it simple:
There are 16 bolts to torque
start in the center of the manifold(closect to air intake plenum) and work out towards the front and back,torquing alternating from drivers side to passenger side. My book says to start at 15ft/lbs and work up in increments to 31ft/lbs total.
