As you're starting to reassemble, make sure you meticulously clean the PC'ed parts on the inside.
Stick them in a bath of hot soapy water, get some long-handled brushes, and get scrubbing
You need to make sure there is *none* of the blast media left in there. More than one 928 engine has been ruined by sucking glass beads in from a freshly PC'ed intake manifold.

I've left some mating surfaces coated and not had an issue.
But I've always cleaned the area under a couple bolt heads for the water bridge to ensure that it gets the needed ground for the sensors.

They would say all surfaces have to be flat, free of damage, clean and oil free. Then they would state the machining tolerances for parts like the coolant bridge.
