If you're running stock steel rockers, you may have wear causing the tip of the rocker to not contact the valve stem squarely causing a light click. Some roller rockers have a tendency to make a bit of ticking noise. What are you running for rockers?

stamped steel, this is my first time adjusting valves, i folowed the procedure to the letter, i would have thought they were perfect but now when its running i can hear them clattr slightly, and i don't get the vacuum reading.
