The most important thing is to make sure you are doing the exact same thing each time you check and adjust the lash. With the Jesel rockers there should not be any change in lash when you check your rockers once all of the parts have been "run in". If something is loose then you have a problem. This is for super stock style engines. I adjust mine using the degree markings on the balancer to make sure I am checking the vales at the exact same point in the engine rotation. Its not so much the process of how they are set. They need to be set consistently the same. That also goes for trying different lash settings. You just need to find a method that you are comfortable with and stick to it.
