Now THERE'S a hell of a thought. Consider a "bar" three inches long with
sensors at 1 and 2 inches. Betcha the temperature at the head (zero inches)
is (temp 1) plus delta (temp 1 minus temp 2).

how about two temp sensors at measured intervals along the insulated bar,
then assuming the temperature gradient is constant along the bar, you can
work out the temp at the cylinder head.
