I've already added ducting, koyo rad, and spal fans. This change removes the heater core radiator bypass and subsequent hot coolant dump into the cold coolant inlet. It only gets hot on tracks that feature lowers speeds, lots of turns, and short straights. (Shenandoah circuit at Summit Point). It was fine on the main circuit. I may or may not have cabin heat after it's all said and done; might have to change the heater core inlet source since it's post thermostat now and might not receive enough pressure differential to facilitate flow.
FWIW- I only did the re-route because I broke the stock front mount stat stem while inspecting the thermostat. One of the bolts was apparently seized to the stem and consequently broke it. I figured it was a good excuse to do the re-route.

The changes that you mention will have benefits (i.e. cooler head, less heat into the inlet, more even temperature distribution (including better cooling of cyl #4)) but unless you add a cooler to the oil system I would expect oil temps and piston temperatures to be higher. SB:>since I don't yet have an oil temp gauge, I don't know what my oil temps are. Thoughts? I am going to bet that your oil temps were higher than your 225 water.
