If you would like to know tightening torques: M6 - 10 Nm (7.4 lbf ft) (bigger ones) M5 - 5 Nm (3.7 lbf ft) (smaller ones) Indicator nuts torque are not stated in the service manual, you should hand tighten them. The OEM 13-10 mm wrench length is small enough not to oversight them. You can use a thread locker on the M6 screws, like Loctite 243 (blue, or medium-strength equivalent).
The contour of the heatshield plate and the milled part were not the same. There was a small interference which you can fix by filing on the plate. I didn't bother with it. Maybe it was a revision problem with the 2 part I don't know. Maybe if you write to them to be sure it is fixed?
