a bad idea to bypass water from the back of the block to the rad as it
is needed to warm the intake side of the engine and reduce its tendency to
go into a mild banana shape.

I think what you are referring to here is the use of the heater port for
cooling.  I put a thermostat in because my coolant temp is just way too
low during long descents.  Even with the thermostat, the coolant temp is
low, but improved.  Probably due to the cabin heat radiator plumbed from
the heater port.

Thermostats  work of course but for lower cooling drag cowl flaps are better.
Perry  is in a unique position with his ducted fan pusher so cowl 
flaps may not be practical in his case.
