looking through the FSM, I cant find any sequence that the intake and exhaust manis should be tightened. Im not looking for torque specs, but rather the pattern I should tighten them.

I really don't think it matters. If it did, it probably be in the fsm.

I don't think there is an outlined pattern in the FSM either. The general rule is to start in the middle, and work out in a clockwise/counterclockwise pattern.

There is a sequence. I will check the FSM if you are worried but it should be center first than a radial pattern to the outer fasteners.

TMS, I thought there was one in there too, but I couldn't find it. Maybe it's in a weird part of the FSM?

There is a torque sequence for most things on the motor even a loosening sequence for some. Obviously some are more important than others but it's usually start in the center and work out in a radial pattern.
