Yep, inertial and vibration as well as thermal expansion/contraction and engine movement. Slip fits are good for thermal expansion, but I'm not sure how well they do with bending.

For the slip fits, the thing that the welder pointed out is that they would be lap joints rather than butt joints. Since we don't have a hydraulic swaging setup or end-finisher, we will be welding the joints. So there will be some overlap on both sides of the joint and any bending force should be a bit more distributed.
