I would say it could be inproperly adjusted valves also. Are they roller rockers or stock rocker arms. Also, until recently, I thought you should have a breather on one side of the motor also. But it was pointed out to me, that in a mildly beefed up or stock motor, that basically causes a vaccum leak at idle. Do away with breather if you have it, or take a hose from that hole back up to the air cleaner. Readjust the rockers using 1/2 to 3/4 turns after finger tight. Also. did you adjust them when both valves on that cylinder were completely closed? If not do so.
