I'm assuming that I can just purchase and install the
     > spark plug ring type sensors for the CHT

Paul, You really don't need "CHT" sensors. The water
temp and pressure or water temps in several locations
would be more useful. If your system has more inputs
you can probably get it re-configured for the water temps,
and oil temps, knowing the temperature differential
across the radiators can give you an excellent indication
of how well your ducting is working. A conventional temp
sender in the engine would be needed as well. Your set-up
probably has that built in to begin with. Good egt location
with that cast iron manifold would be in the down pipe as
close as you can put it. (That would be if there is only 1
temp probe.) If there are 2 probes a swagelock style fitting
in the wall of the manifold opposite the ports would be good
if the probes are safe to over 1700°F.
Good Luck hope to hear that you are flying soon!
