Mini, Possibly, maybe he'll tell us but thats not what he says and it still doesnt stack up.
Conventional wisdom does suggest 180F a good operating temp for Lycoming engines,

Also 50 deg below 180deg C is 130deg C - way above the red line.
Also 180 deg C is a little cool for CHT. You would be very lucky to keep all the heads to 180C or 356F.
Its easy to press the C key instead of the F. No criticism implied.
