Those figures you gave are just for the ring gap? My bore is about 3-1/8" which would be about .021-.023" for ring gap.
Those figures I quoted were for piston to wall clearance rather than ring gaps.
I sent the second rings to Total Seal and had them convert them to gapless. I'm also having the pistons coated with ceramic on the tops and the moly on the skirts.
Other guys running these engines typically see EGTs in the 1700 range.
Still need a figure for piston to wall clearance. I'm running standard pistons but I'll have the cylinders honed for more clearance.
