I always use plastigauge when replacing bearings on any engine. Installing new bearings and hoping they are within spec is not a great idea although you might get away with it sometimes. If you match the bearings with the chart in the service manual they will probably be correct, but always a good idea to make sure before assembling the engine.

Warping the case by using plastigauge? They must be confused.. the plastigauge is used to check bearing clearances by placing pieces of it in the journals and tightening the bearing caps on top of it. It's a very soft plastic material that cannot damage anything.. no chance of warping the case.

Yeah it shouldn't really be a factor anyways since you only have to torque the bearing caps down & then remove them to use the plastigauge. You don't have to actually bolt the cases back together or assemble the engine to check clearances.
Either way I would not assemble an engine using new bearings without checking the clearances first
