More expert voices will know this for sure, but watching my engine build as part of the Aero Sport Power Build School gives me a hint: yes.
Apparently, those bolts need to be stretched since they are torqued on both ends. During the build, we actually adjusted the apparent "extra" bolt beyond the nut until they were about even on both sides, then BOTH nuts were torqued simultaneously to the correct torque.
I watched this done by two technicians at the same time several times. Each would torque their nut (on opposite sides of the case) , using one of those "bendy" not "clicky" torque wrenches and say "Now!" when they got the torque they needed. Neither of them let go until the second "Now!" was heard.
So, that's the witness statement of a moderately qualified person. Now, let's hear from the fully qualified.
