Ok, here we go! Get on your thinking caps. Some people say installed height is not a big deal. They will all open as much as they should! Yes, kinda true! Lets just stop this internet bullshit discussion now! Installed Height is Super Critical! Not all pushrods are different lenghts. They cannot get proper Rocker Arm Geometry without each valve being the same height above the deck of the head or engine surface. Sure you could run shorter or longer pushrods as the position dictates! Did I type Pain in the Ass?
