The idle is rough when the engine is under load and at idle? I' guessing here, but you could check the timing, and check the plugs to see if any are fouled or not gapped correctly. Also when did you last check/adjust valve clearances? Check for operation of EGR and PVC valves
Good luck.
welcome to the board there is alot of good heads here someone will probably have an answer for you.
