all the LS'es ... workshop manuals, electrical wiring ... all years all models ... also available on DVD.

Hey Joe is there a torque sequence for the 3.9? I just torqued my Intake Manifold down a half a turn at a time on each bolt head in a circular pattern. Like making laps around the Manifold. Did I f*** up?

Maybe, maybe not. The engineers define a sequence that causes the least stress and best seating for the parts. Often times, there is more than one good sequence to use, but they only indicate one. However, my guess is that the circular pattern was less then ideal. It's done now, you'll just have to see how it works out. (It'll probably be okay.)
For next time, here's the correct sequence for you (item 25).

I would retorque it now according to the procedure. Ford plastic intakes are known for cracking, so it is more critical that you torque the intake according to sequence. Otherwise, you'll be replacing it before long and they aren't cheap. When you tighten a bolt, it sends stress from that bolt out to the other bolt points. Each time a bolt is tightened, any force it received will be partially moved to the next one down. What this results in is a lot of stress between the first few bolts and the last few bolts in the sequence.
When in doubt on the torque sequence, torqueing sequences usually seek to start in the middle, and work their way out. There is usually also only two, maybe three torque steps involved. The first sequence correctly seats the part, the second sequence clamps it in. If there is a third sequence, it'll usually be due to mismatched material types, like not steel/steel or plastic/plastic.
