On my 2nd gen engines I saw a small drop (~2 degrees? ) in temp from under oil filter to water pump outlet that I attributed to cooling on inlet side of engine.  The Renesis is a different story where I see a 3-5 degree  increase due to heating from the longer exhaust ports.
 
BTW,  CONGRATS to Al on first flight of his plane.  It is one of the most meticulously built machines I've ever seen (in pictures).  Hope I get to see it in person someday.

I don't know George? I just report the facts. The water temps are 
measured when the coolant comes from the block (hottest) and the oil 
after the cooler (coolest). Don't ask me why :)
