Nah, timing it isn't that hard, you just line up the marks like any other OHC engine - just follow the directions carefully and double and triple check everything.
Like I said, it's straightforward but time consuming and a couple of steps will test your patience and the depth of your four-letter word vocabulary (hello Mr. Fourth Power Steering Pump Bolt
) but if you've got skilled mechanics to help you out, you should be fine.
It's a pain in the ass if you've got cams with press-on sprockets or your doing it without the timing chain wedge tool because of having to take the timing cover and the chains off - adds hours to what could be a pretty easy job otherwise...
It's been a while since I did mine so the details are hazy but one big tip is that your repair manual may instruct to remove the oil pan - that's not necessary, you just need to remove the bolts in the front of the pan so that you can slip the cover out.
You'll want a good assortment of regular and deepwell metric sockets, a universal joint and an assortment of extensions.
The valve covers are tricky to get back on without snagging the gaskets on something and pulling them out, or gravity pulling them out. Run a thin bead of RTV in the groove in the covers and put the gaskets in and let it cure and that will make it easier to get the covers on with the gaskets in place - it'll also help with the tendency of the gasket to want to pop out in one place while you're popping it in in another. You don't need a bunch of RTV, just enough to hold it place.
