I think you are getting taken. I can't believe that
you would see that type of corrossion on new heads in
such a short time. I;ve worked on many WBX engines,
and there is always corrossion, but never to the
extent in the time period you refer to - perhaps after
60-70k.
That being said, I do agree with the tech that VW
original coolant is the best. Its the only thing I
use. Taking apart an engine that has run on it after
many years is a beautiful thing - no corrossion.
