Blue,
Welcome to VAF. A couple points for general reference (as others have noted, there is quite a bit of variability in both parameters):
I run a Superior IO360 in my 9 and CHTs vary with OAT. Typical summer day at 65 degrees OAT, 8000 ft DA, I see around 340-350 on CHT, lower if throttled back. As noted, EGTs are only relative. Mine are mounted about 6" below the cylinder (not optimal, I know) and run around 1450 peak. At low altitude, I sometimes see them over 1500 at peak.
cheers,
greg
