At 200k take the opportunity to check the bearing bracket that holds the fan clutch. If its never been replaced, you'll likely find quite some play and if you do, get her replaced now since it'll take 10mins to do it. The fan clutch should have no play and spin perfectly straight.

Glad to hear you left the intake manifold alone -- its just sooo much easier for the sake of less potential headaches.

How do your timing chain guides look?
