Gregg,

Was the head leaking really bad before you changed it?  I've had
exhaust systems with enough coolant dumped inside they take a good
drive and heating to burn off completely.  I had an S4 I did turbos on
that smoked for a week from the oil in the cats.

The link to the video didn't work for me.
