You can buy some Loctite from the company I work for

[looneytuner]

do you have the turbo support bracket in there?
Also check with FWD or MPGMike about oversize studs. I have one of his heads and it looks like he installed os studs. The gasket doesn't have slop on the studs like the stock studs do. I'm guessing the bolts are wobbly when you start them by now. IE the threads in the head are wasted a little.
You also need liquid teflon on the studs or bolts NOT loctite.
