eq magnum rockers

The pictures shown are basically worthless and show nothing meaningful. The rocker needs set where the pivot from fulcrum to tip roller is at 90° to the valve stem, then you lower the rocker half of your valve lift total. That is when you measure for pushrod length. And add your desired preload
It doesn't matter wat length the rod is the rocker design will not let everything mesh together if you get the fulcrom and tip at the 90 angle thepushrod is way out of it's range and if you correct that then the tip is off the stem.I tried the adj rod at every length I could and you can get 2 things right but like a rubix cube theres always one that won't get in line lol
