I agree with your concerns . Paul was involved in picking out the new rocker arms. I was not involved in the installation but remember some concerns being mentioned about pushrod length. There was no discussion about changing the pushrods to match the new rocker arms from Paul’s side so I guess everyone assumed that it was a good match. I can’t help but feel we are getting close to identifying this problem. The best thing would be if PAUL could get his hands on the motor. But that’s no easy request
