I believe the factory started grinding either the apex seals or the housing surface that way for better fit while running.

i'm not sure where this is mentioned, but a new factory apex seal isn't flat, its bowed slightly, so that when its in a working engine and up to temp its flat.
another problem on used housings, this is why they shrink, and why we measure for width, is that the steel liner actually collapses in the compression area, so the center of the housing bows in. its very bad to have leakage between chambers...
