It depends on who's quoting. I don't think Lyc. reuses cams on their
overhauls. I just had a Superior Millenium overhaul done on my O-360
and the price included a new cam. Their take was that the overhaul is
being done to new specs and a reground cam will not meet new specs.

A quick search didn't find any statement from Lycoming itself, but this article

says:
"Lycoming offers both factory remanufactured and overhauled engines.
Remanufactured engines have essentially all-new parts but may use some major
overhauled components such as cases, crankshaft, and accessory gears. Lycoming
builds remans with new cylinders, pistons, camshafts, and ancillaries like the
oil pump. With the Lycoming overhaul, you may end up with more used, overhauled
parts..."
