Thanks for the added info. So you trim the studs, then after you install & adjust the rocker's you make sure the rocker balls are riding on solid stud and not threads, and if necessary you can add a Grade 8 washer under the stud to raise it up, right? If it's riding too high on the studs for a washer or two to get you on the solid stud, would that point to the need for a shorter pushrod? Why not just start with a washer, and then trim the bottom only if your rocker ball rides too low up top? I'm not questioning the process - just reasoning and asking questions.
