[RICK LAKE]

Jon Miller John couple of things If you are breaking in the motor, REMOVE the inners for break in. It is alot easier in the valvetrain. A couple of bottles of EOS from a gm store. Heavy rocker shafts also. With that .572" lift cam you are pushing hard on the stock system. I just broke the shaft assembly with a .501-.533" hyrdo lift cam and damaged 1 head and some valves. Buy the heavy duty shafts. I thought the same way as you. There was nothing wrong with the setup or alignment. the shaft just broke at the stud mount hole. Rick Lake
