The reason for degreasing and inserting dry studs is that the stud will be stressed correctly when it is torqued up, not grossly overdone as it might be with some fancy lubricant, or underdone. The threads need to be properly tight so they all share the load, cast iron not being nearly as strong as the HT stud. And yes, they should be torqued up, not just finger tight. It is easy to do with the double nut technique. Just do not exceed 30 lb ft as you tighten the two nuts (3/8" UNF ie head huts) back to back, and use the torque wrench on the top nut to get 20 lb ft between stud and block. Then the load will be distributed reasonably well between stud and block.
