Individual header tube temp. Egt. Varies

Hi all,

Anyone ever paid any attention to individual egt per each individual tube on a sb?

I bought a cheap infrared temp gun, and all my cylinders range at idle from 180 degrees F clear up to 280. 1,3,7, 2,6 all seem to be 180.
#8 is actually always my hottest. Clear up to 280. Then #5 and 4 are more like 220.

Is the temp on 8 just the typical lean cylinder of the way a sb flows? Or i have more going on?
