I won't try to put words in Tony's mouth Steve, but it's possible for a block or a head to have a cavernous hollow inside but no measurable gap at the edges. Testing around the edges with feelers alone may not be enough.
Anyway my thinnest feeler gauge is 1.5 thou, if I could measure 0.004 I think I'd keep on lapping.
