I just saw on excellent utube vid on this. (1) be at TDC #1 compression. (2) snug all rockers to zero lash. (3) turn crank 90 deg & adj all loose pushrods to zero lash. (4) turn crank 90 deg & again adj all loose rockers to zero lash. (5) repeat 5 more times. (6) add preload to all 16 rockers. you're done. later I will post the name of it so you can check it out your self, I was impressed. EDIT "hydraulic valve adjustment made easy-your engine guy". "Ellisons machine shop-your engine guy". check it out & see what you think. RR
