The big thing that I worry about is the girdle physically moving forward/backwards under load with the shank of the studs being reduced. There is a significant enough difference there that I am not comfortable with. I know these are tq'd to 74/75ftlbs but realistically speaking we are pushing these assemblies more and more and I want all my pieces to line up and fit as they should without worrying about details like this that "could" not saying they "will" but could, cause issues. The responsibility I have is extreme so I have to ensure everything I do is 100%.
