So far so good. I don't think it leaks. I used studs and Right Stuff, per my prior post. I retorqued it several times (once after each of the first few heat cycles, and then once per week), but the nuts still seem to get a little looser and tighten up by about 1/8 turn each time I retorque. By now they should've settled and the gaskets should be fully compressed by now.

So my question is: anything wrong with using double nuts on each stud to keep things tight? Or is it the studs themselves and not the nuts that might be loosening?
