So what is the temp. difference, in round numbers? I'm curious too...

I would think the head temps would be higher than lower down in the
block; most of the heat goes out through the head; that's where
combustion is of course but the expanded gases down in the falling
cylinder have the heat sucked out. Water flow is suckier in the head
too.

You might have a hot spot, normal or otherwise. All I know is, temp.
distribution in a cylinder head is complicated :-)
