In August 2007 my car, a '92 VR6 blew the head gasket a few days after turning the boost up a bit. It was really just a matter of time and I fault the stock gasket with 168k miles on it more than the added boost.
I decided to tear it all apart over the winter and rebuild it with a bunch of "while you're in there" go fast and maintenance parts. It's gotten a little out of hand since that day in August. A lot of work has been done over the winter, so I'll do my best to back log most of it and then post updates as I get this thing back on the road by June 7th, 2008.
