I mis-spoke. Instead of actually "decking" the block again to bring it all even, the shop took a machine file to the area and took the fill-in areas down to deck height. The entire surface was not ground down, only the fill spots, then measured with a gauge to determine tolerance.

A re-decking involves disassembling the entire block- This machining was done with the shortblock still assembled, and the rest of the ports sealed with tape to avoid contamination.
