Since installing an EDM 700 I notice my cylinders running around the 380 to 415 deg C

Number 1       380 deg C
Number 2       380-398 deg C

Number 3       380-395 deg C
Number 4       415 deg C

Number 4 reaches 430-450 in the climb out at 130 KIAS

I am thinking of putting 2 NACA ducts in the top cowl to address particularly NO 3 & 4 temps

What say ya'll
