Torque Sequence and Specification- V8 intake plenum Please

[Crashroland]

I have a 2007 S80 V8 but am posting here because of the engine shared with the XC90 V8. I am hoping that someone can share the torque specification and tightening sequence for the (20) 6mm hex bolts that fasten the intake plenum at the top of the engine. I am planning to replace the fuel pressure regulator and will be posting instructions and images for the procedure. Thanks in advance for your replies.

You do not need to remove the plenum to replace the Fuel Pressure Sensor (FPS). You just need to unscrew or cut off the small (I think M3 or so) bolt that holds it on the FPS mount. It's a tight reach, admittedly. My bolt would not back out, I partly cut it with a Dremel with a cutoff wheel and after getting partway through decided to try backing the bolt out, which apparently worked due to heating the bolt.
