One thing other than pulling the intake and replacing the O rings to watch for on this engine is guide wear that causes rough idle. With this milage I wouldn't be suprised to see it needing a valve job, not to mention the potential for cams, rockers or a fuel head, unfortunatly the guides are noly seen with the heads pulled and stripped, (springs, seals etc...) you might be in for a long haul getting the idle straight but, every one of these I've seen get the top ends done ran super afterwards.
