Re: 289 idle
Check the intake valve that has the weird adjustment, and see if the rocker arm stud has pulled out of the head somewhat. The rocker arm studs are just pressed in on 289's. There are aftermarket screw-in studs available, or if you are careful, you can drill a small hole and pin the problem stud. Either way, this may settle the valve adjustment problem, but as to the bad idle???
