Do you think in Europe everyone is worried about when their cylinders hit 204.444 celsius? I think people get hung up on 400 degrees simply because it isn't in the 300 range anymore.

Looks like at 350 we better stop flying.

With my limited patience, I cannot seem to find the strength vs temp charts for various aluminum alloys.  Here is some data for 2124-T851.
As I remember the cast alloy for our cylinder heads is worse than this and the curve gets steeper as you increase the temp past 400 degF.
Look at the second chart carefully and then consider cruising with 420 degF CHT’s.
