I've got my engine out and am getting ready to start taking it apart so I wanted to start this thread to ask a million questions lol.

My first question is on the timing chain kit. It's the only thing I have yet to order because Im not sure if mine has a balance shaft but I'm hearing that even if it does, I can just delete it? That would save a few bucks on the kit and a little less work. Any downsides to that?

Next, is there any reason to take the exhaust manifolds off the heads if I'm just taking the heads off and putting them back on with new gaskets (I hope!). If there's a good reason to I don't mind doing that but again trying to save some (maybe a lot) work.

Was contemplating leaving the camshafts in place to but I think it'll be better just to take them out and reinstall for the timing process? I bought a valve compressor tool to get the roller followers out that allegedly is specifically for the 4.0 SOHC so hopefully that'll make it a smooth process. Unless of course it's smart to just leave them in?

You can see in the photo, the top right arm of my engine stand is in the way of the rear timing chain bolt. You think it's safe to remove that arm when it comes time to remove and replace that bolt? It just seems like a lot of engine already on 4 m10 bolts and then to remove one so it's only hanging by 3...? I couldn't find a better way to position my engine stand, it's the small harbor freight variety.

Also taking bets. My truck has 115,000 on it, will there be any broken timing chain guides?🤔. Thanks guys, I'll have a bunch more questions as I tear into this thing.

The heads are heavy so removing the manifolds makes them more manageable. You'll need to clean the head/deck mating surfaces (at least).

Removing the manifolds is a can of worms for sure, but it might not be terrible to remove them while you have the engine out so if any studs break you will have better access for replacing and then slather them with anti-seize before re-installing. That's what I would be thinking about anyway.
