Ok so take temps after landing and shut off and the temps should be about 180F at the head. The engine will get hotter as it sits for a few minutes but then it will cool off. You want to know what the peak heatsoak temp is too. If you have telemetry it would be good to add it to the top cylinder and get some info in flight. As long as it's running smoothly with a little gray smoke and good temps it will be fine.
