Windage Tray Stud kit install Q's

What a machine shop told me about the main bolts: put 30 wt. oil on the threads and torque to specs.
What I have gleaned from FABO regarding the bolts to hang the windage tray: use loctite and torque to specs.
I wish crazy 340 had made his findings public sooner, my oil pan has already been installed.
