At what fuel flows and
speeds?
I use 2500 and 31 inches
about 27 GPH. It was my understanding that continuous operation at 38
inches was not recommended. I have not tried to climb at that setup,
it might run cooler.
My baffles and fuel flow
have been very carefully looked at. Working on the baffles made a definite
improvement.

I
climb at 30 to 31 inches 2500 rpm to get to FL 250. I manage my airspeed to
maintain CHTs at 400 degrees (or less) I can only climb 800 to 1000 fpm
continuously at about 160 to 180 kts depending on temperature. I can climb
faster for short periods. The power is there, with better engine cooling
faster climb at lower airspeeds would be
possible.
I suspect your engine fuel flow and baffling are not set up correctly. You
should be able to climb continuously to altitude at 38.5 inches and 2700 RPM (at
WOT) and keep your cylinder heads below 380F. If not then you have some work to
do.
