If I may offer this: The reason I asked about your head gasket is because you did as I suspected. Just my $.02 here on your work....but when you loosened the nuts, you should have removed the head, re-annealed the copper gasket, and reinstalled and torqued. Once the torque is removed from copper, it will not properly reseal (combustion pressures)unless it is replaced with a new one, or annealed to soften it back up. In a turbo motor such as yours, this is imperative because of the increased combustion temps.
Again, just my $.02 from years of building air cooled stuff... If you want to know of a good annealing process, I'd be gld to offer.
