Oil Pump Pickup Tube Install Using Temperature Difference

I have done some research on this topic over last day and it seems that one method of installing an oil pickup tube into an oil pump employs the physics of temperature difference between the two mating points.

So was wondering if I place pump in an oven @ 200 degrees (which is what the typical operating temp of the engine is, at least according to temp gauge) and pick up tube in the freezer for similar time periods, say half an hour, would there be some damage done to either piece that leave them inoperable?

just searched dont seem like any pumps come with it installed ,mostliklely its just a tap in procedure and there looks to be a bolt that bolts the pick up tube to the block keeping it from falling out of the pump .
