While both our temps are above the nominal recommended, I have found that
for short duration, there does not APPEAR to be any problem.  I know Tracy
encounters (or did with the old 13B) the same conditions with no apparent
problems.  I think we would both feel a bit more comfortable with temps that
stayed below 200F (and I do use that as my max red line for oil), they only
way I know to do that is to size your coolant system for climb conditions
which means it will be oversized for cruise with resulting excessive drag.

Ed,

 

Consider the air exhaust rather than considering the intake sizes. Air, in a cooling system does not act the way we think it does. If it doesn't like the flow pattern, it will stop.

 

You can use a manometer (make it out a clear tube) to look at air pressure differentials. Don't forget about cowl flaps.

 

Keep cool
