Head Gasket Leak

Like the title says I have a head gasket leak on my Turbocharged Zetec Cougar. Oil film in coolant reservior, Coolant in oil pan, moisture in cylinders, and pressurized coolant system are all of the tell tale signs I have. It got to the point where the car wouldn't start, which I think was caused by the moisture in the cylinders.

So, I wanted to ask if anyone has any suggestions as to what might have caused the leak or what I could do to help prevent it. I am running about 16psi max boost on a 8.5:1 C/R engine with a Cometic gasket and ARP Head Studs. The head studs were never "re-torqued". I received an email response from ARP saying that depending on the head gasket I may be required to do a re-torque after the engine has been brought up to temp and cooled down, and they definately recommend re-torquing anyway.

There was only about a tablespoon worth of coolant in the engine oil, so at this point I think I am going to just try re-torquing the studs. In the email the ARP rep said to torque to 60ft-lb with ARP lube and 70ft-lb with 30wt oil. These numbers don't seem entirely consistent with what I have seen on here and the jet.
