Coming from the old school;} I was told to change the plugs on a BRRRrrrr cold block. It's always worked for me.

Well, I can see two schools of thought on this, both of which seem logical.
In one scenario, the head would expand into open spaces, meaning the size of
the threaded opening would shrink, making the plug more difficult to get
out.
However, if the metal expands relationally (meaning the entire piece
basically scales up to a larger size), the hole would become bigger as well.
If someone hadn't stolen my digital caliper, I could measure a hole in a
piece of metal both cool and hot to see what actually happens, but I'm sure
someone here already knows. Anyone?
