Ok, just got off the phone with the shop. They offered to dissassemble 
head & remove the paint. I said to please do so. (I will not pay for 

Here's what he said about the rest: they've done dozens of VW 
diesels, and they all come out with a small amount of scoring from 
material coming off the precups, even though they do it wet. He said a 
mirror smooth finish would require their diamond cutter, and the 
precups will destroy the cutter (is this true? I though diamond was 
pretty hard...). He assured me they have not had any problems with 
VW diesels heads done like this. 
He also said the cracked precup was not a problem, and that 
replacing & machining one to fit would be 1.5 hours. He says they 
often are cracked, and do not cause a problem. 
I will try to pick it up later today and take some pics.

On the plus side, the welding job they did on the coolant cavity 
appears excellent - I had a hard time even spotting it.
