[Fot] EGT readings

[Russ Moore]

I target 1350 but only at the end of a straight, Anything else I ignore. 
When I ran stock pistons 1400 degrees was the fear point. Your situation may 
be different. This was on a 1296 Spitfire comfortable at 7800+ rpm and we 
ran a 34 degree total advance with twin HS-4 SUs.
I run a thermister on pipes 1 and 4 of the headers and can see immediately 
if the carbs are not in perfect synch.
