    Re-check the valve lash would be a good starting point.
    If ya can't fix it with a hammer,ya got yourself an electrical problem.

      Lets back up a second. Why did you replace the heads?

        I had a ticking typically on startup and until warmed up. Several months ago. Last week powerhead lost power at 4000 RPM and I had idled it back to the ramp. Will remove cylinder heads tonite off the powerhead that is on a dolley in the garage. I'll report on block damage soon. Metal in oil pan resembled ring damage.

          When you do report, do it in a new thread. Look how old this one is and the OP never came back. We'll close this one now.
