Dave your numbers pretty much match my M-10 / C90 - 16F under the conditions described and the mixture full rich. You will be able to significantly bring the numbers better in line and reduce the difference between the hottest cyl. and the coolest cyl. when leaning agressively. Usually I can get the temperature difference down to less than 100 degr. F. Leaning will increase the temps in cyls 1 & 2, while those in 3 & 4 are fairly constant. This process of leaning also brings down the fuel consumption considerably, on average by about 15%. I have a series of values on my web site www.hpo.net/users/sfanselow/m10 Click at the link "EGT/CHT/Fuel" for more details.
