James, if there are 3/8 inch studs they will handle 40-50 ft/lb. If they are 7/16 studs they will take 60-70 ft/lb. IF THEY ARE NEW. If you have rusted studs of uncertain age and strength I would just tighten them till I feel resistance, then a bit more, then start it up and check for leaks and if necessary, tighten a little more till you here the leak get quiet. Last thing you want to do is break one off.

That would be right. Grade 8? Put some anti seize on them no matter what you use.
