I really like this lesson on Geometry. I bolded the last sentence because nobody ever told me this, they just say $hit like "tighten them all the way down and forget it". Hate it when they don't explain why, you don't learn without the explanation. To me this is the crucial step in helping others on these forums and without explanation with your opinions you might as well not even post at all.

Geometry Lesson
All pushrod engines that pivot a rocker arm on a stud determine the location of the rocker-arm tip relative to the valve tip with pushrod length. The small-block Chevy, along with many other production engines, originally came equipped with stamped-steel rocker arms. These rockers used a very wide rocker tip with a very gentle radius that was extremely forgiving when it came to pushrod length. The pushrod length could be short or long and the broad rocker-arm tip would accommodate it.
