First annual and I'm questioning one of my exhaust valves. Any input would be appreciated. 175 tach hours on the motor, compressions came back 79/78/78/77 on a cold motor.
Everything looks good and great photos. Which horoscope are you using?
Vividia ablescope VA-400 connected to a Pixel 2XL phone. It's usable on any laptop or android phone. Not compatible with iphones or ipads.
Exhaust valves look normal to me. The exhaust you have two pictures of of may be running a little hotter but not on on the heating diameter which is the important area.
Does this engine have the 3 angle valve job on the intakes like the 340?
Third photo, the exhaust valve (that's the smaller valve), there is a brown patch on the lower right edge. Anything asymmetric on exhaust valves is a caution, particularly near the edge. I'd want to keep an eye on this. Maybe re-check that one in 10 hours. If it actually is a problem they can go south quickly.
Engine monitor? If so upload data to a free account at Saavy and see if the EGT signature is happening.
They look OK to me. I think that brown patch is just some lead build up. But no harm in checking at next oil change.

The more informed can correct me if I'm wrong, but I don't think there's necessarily a correlation between "hot cylinder" and exhaust valve issues. I'd actually think a leaking exhaust valve (if you had one) would result in cooler CHT as some of the heat is leaking out. Anyhow that's my hunch.
