Can we get a more definitive answer as to George Braly's comment on the IO
550N running too hot? I typically climb my IO 550G Lancair IV out at 2500
and full throttle,indicating around 140 knots and see my hottest cylinder at
375 to 390 degrees. Is that too hot? I have the baffling kit from Lancair
(delivered in 1998), is it different than the Columbia or Current Lancair
Issue?, or is my climb-out speed higher? My lancair IV uses the ES cowling
with the smaller air inlets.

(The engine runs too hot in general.  There are several reasons for that.
One, the POH recommends 25 squared for climb, which is a very bad idea.)
