We've done that as well with a surface measurement spotchecking the cooling

Once you've installed a pyrometer in the manifold or exhaust
system to measure the temperature of the exhaust
gasses, there's no going back, you'll love it. Instant feedback on the range you're operating the engine
in and importantly you can see how loaded it really is.
