Fred,

My CHTs are running at between 320=B0F and 390=B0F in cruise(depending =
on=20
the power setting and OAT) and up to 430=B0F in climb. I have 1,000 =
hours=20
on the engine and it still looks perfect from a compression and oil=20
consumption point of view. What are we doing so differently?

Oh... I just saw your centigrade indication.
