Stupid machining question -cylinder head

I seem to recall when I was a kid the NAPA store in town resurfaced cylinder heads by setting them on a black and decker belt sander with some sort of jig.
Or am I losing my mind?
Nope. There are surfacing machines like that. They aren't as accurite as a mill but for a little surfacing and not milling a lot of material off, they worked ok. Great for surfacing exhaust manifolds. They are surfacer and not a mill.
