George,

Four probe JPI EDM 700 - I wish I had six cylinders
  
<<  Did you notice that the CHT went up?>>
No I didn't, but then again I wasn't actively trying to compare like EGTs, altitude and OAT to see if the combination was producing higher than normal CHTs.  The delta, if there was one, was small enough that I didn't suspect anything.    I often wondered if all the damage occurred only during take-offs at high power.  The transient nature at takeoff would have more easily masked a higher than normal CHT.  This was late summer with OATs in the 90's-100's.
