Cylinder head - donor needed ... maybe not

Hi everyone,
Just an update on my '89 100 ...
I've pulled the head and am optimistically thinking that all I need is a
head gasket.  It appears the head is still flat and there is no sign of
cracking or other damage.  Close inspection of the gasket does not reveal
any obvious point of failure.

After pulling the head I realized I didn't really know what I'm looking at
so consulted with ace local Audi specialist Bo at Acceleration on N High St
here in Columbus.  He said that 98% of the time when this happens the head
gasket is all that's needed.  He also suggested that the blown heater core
may be the result of a blown head gasket ... maybe the gasket failed first.

So I've got the interior all cleaned up ... pulled the carpet, washed
everything, dried and put back together.  Next is put the engine back
together.  I don't plan to do any head refurbishment because the thing ran
great up til now.   Then on to the heater core replacement.
