Is it purely a function of the size of the metal piece, or is the type of
metal part of the equation?

The other thing I don't understand is that if I do a good job of insulating
the metal piece from ambient how it won't eventually come to the same
temperature as the head.

Thermo and I never did get along very well.

Attach the sensor to a piece of metal. Bolt the metal to something on the
cylinder head. Wrap the metal/sensor with insulating tape to keep cooling
air off it. Change the size of the metal piece to vary the temperature
ratio.
