The 200F mentioned is a normal engine temp.
300F oil sump would be near meltdown but it should still survive.
I would personally not hesitate to use 200-300F...the pulley will cool some by the time you get it from the oven and positioned/ready to press.
IMHO a person is cheating themselves by purposefully loosening the fit of the crank pulley on any engine as I personally believe they were designed to be tight. While the engine rotation appears smooth it is jagged as can be from a torque impulse standpoint.
Also consider the cost of having a pulley get "loose" and start knocking around into the key....which wallers the keyway by the time it is discovered...which means get a new crankshaft and do a major engine teardown. Not worth it in my opinion.
