So, the cylinder that I am working on has to be at tdc? Also, are they just torqed down once I am on the right cylinder? If it is on #1tdc, can't I just go throught the firing order? I dunna know, I could just be all wrong. I have the destructions that came with them, they are very general and the image appears to be a chevy engine?

Ok heres the way I set rockers. One thing that helps a lot is if you have a remote starter to spin the motor. Basically what I so is set up all the roller rockers on the motor with the bolts tight enough to show the position of the rocker and the valves. Than starting with the first cylinder spin the motor till one valve is completely open. Slowly tap the remote starter until the rocker stops pushing the valve down. When you reach a point where the rocker is neither moving down or on its way back up you know the valve is completely open. At this point adjust the opposite rocker as you know the valve on this rocker is fully closed. Your going to want to tighten it down to where there is zero lash. This meaning there is no gap from the lifter through the pushrod into the rocker. A good method here is to tighten down until you cannot spin the pushrod than back it off just a hair. At this point I turn the bolt 3/4 to 7/8 of a turn to set the proper pre-load. If you get more turns than that you need to add a shim under the pedestal. If you get less than 3/4's of a turn here you need to have the pedestals machined down some, this is uncommon but does happen. I than adjust the rest of the rockers the same as the first two I just mentioned. There is a way to do multiple rocker sets at a time but I like to do one cylinder at a time to really get a feel for how things are set. Hope this helps and good luck

Just a note, theres many methods in doing this as I mentioned. I have done it this way for a long time now and have never had a set of rockers rattle or make noise upon fire up.
