Good news on both accounts (EGT's and coolant flow). Thank you, AL.  Paul Conner, temporarily grounded due to hairline crack in fiberglass nosegear leg.

When I increased the throttle to 5300 rpm's in level flight, temps slowly started rising. I then noted the EGT at 5300 rpm's. It was 1425.  Does this sound a little too high?  If so, my mixture settings may be a little lean at those rpm's.  Just wondering what others are seeing for EFT temps for around 5300 rpm's.  Thanks in advance for any and all replies.  Paul Conner

 

Paul;

 

The EGT depends on your operating conditions, of course; but are not too high.  I found on the dyno that at max power mixture (rich of peak) and WOT at 5300 the temps were right about 1550F.

 

I also found that the coolant flow rate is 35-40% higher without a thermostat than with.  So it is no surprise that your running cooler.
