Interesting to hear of the bolt hole cleaning.
I remember replacing the head on my Rabbit 1.6 NA (1.5? can't remember....)
After I did the job, it worked fine. Car had a new rad, water pump
etc. etc. I sold it to a friends kid, but since I'd never replaced a
diesel head before, the price was *very* fair.
The kid, car and I went to a VW dealership to have my work checked
out. (he knew the mechanic). The mechanic asked if I had cleanded the
bolt holes. "uh, no". I didn't even think that IF there was a little
oil or whatever in a hole that the head bolt would create a LOT of
pressure. Add heat to that, and whamo. Possibly a crack.
