In a sense, you're probably right. There's a threaded hole in the
cylinder head. The probe goes there, no matter what the airframe. The
only way the airframe could make a difference is if a) they have the
probe in only one cylinder and b) the temperatures on the other
cylinders are known to be significantly different.

Actually, it can make a difference even beyond that. The fine folks at
GAMI (as part of their liquid air project) completely instrumented a few
cylinders (dozens of probes each) and went flying. They found 80
degree differences from one side of some cylinders to the other side.
So even a threaded CHT probe may or may not be telling you the true
temperature of even THAT cylinder.

FWIW, GAMI theorizes that this uneven cooling air around each cylinder
may be a significant cause of the cylinder operating "out of round" and
causing significant scuffing and wear.
