Any flying a C182S with all six cylinders being monitored, what are you
seeing for CHT's EGT's(corresponding power settings and fuel flows)?
At 65% power 23" MP and 2300 RPM I am seeing 1400 deg F CHT's and 410
deg F CHT's with fuel flows lean of peak about 12-13 gph.

Whoa! Lycoming engines are recommended to be run at CHTs of 400 deg F
or below. And Lycoming does not recommend running the engine lean of
peak. To quote from one of their publications:

"The fact is that the technique of operating lean of peak and power
recovery was discontinued due to the resulting increase in service
issues. Burned pistons, valves, ruined rod and main bearings were
traced to the inability of pilots to utilize this technique with the
instrumentation and distractions found in the typical general aviation
aircraft. If Lycoming felt that this was indeed an efficient and
reliable method of operation, you can be sure that it would be in our
recommended procedures."
