91 100 ISV & URQ rebuild

[DGraber460@aol.com]

God smiled on my Audi efforts today. The 91 100 idle problem is rectified, 
and the head is now off the URQ. Tremendous relief in both cases.
91,100 was merely my cleaning of the ISV had imparted a slight nick on the 
rotary barrel in the unit. Looked fine and free before install, however it 
stuck closed upon use. Removed, freed it up, removed the burr, and it works 
fine now. Thanks bunches to everyone that responded!
 
After much gnashing of teeth, the URQ head is on the bench, with a nasty 
penetrating groove in the #2 exhaust valve. I've seen pictures of this sort 
of thing before, but never encountered one personally. I don't have access to 
a digital camera, but I think I can have my film copied to disk and post a 
photo. As much of a bummer as this has been, it's nice to find an obvious 
reason for any malfunction.

Any Denver area listers have recommendations for a head/machine/engine shop 
to take the head for renewal?

Not so desperate (in fact quite happy) in Denver.
