My question is on the job to replace the timing device. I see in this thread that the bolt is apparently reverse thread, that is good to know! But is this a job for a reasonably competent DIYer? Once the bolt is removed, what is the next step? From the photos in the thread the chain needs to be secured, the shaft is splined, is it just a matter of securing the chain, taking the bolt off, sliding the timing device forward to remove, and replacing? It would seem that the chain tension might be a problem. I'm sure this must be more difficult.
I need to decide whether to flatbed to my indy or tackle this myself.

Chris,
Sorry to hear about your predicament. I'd say this is an advanced DIY project. A few special tools are needed, nothing expensive, but you'd want to plan on the job taking a week or two... pretty likely you'll run into some problem or another and have to wait a few days for parts, etc. The procedure for the 606 engine is
here. However that procedure is pretty cryptic... the 603 procedure is much more detailed (and should be very, very similar)...
click here to read that one.
You need to pull the valve cover off, unscrew chain tensioner, mark & remove the cam sprocket, allow the chain to pull into the cavity, pull the dowel pin out of the cover so the chain can unhook from the timer sprocket, and wiggle it out of there. And of course you'll have to take off the fan clutch, serp belt, etc to access the pump. Don't forget to clean out the oil pan... since your 606 doesn't have the side-access sump like the 602/603, this will be a real challenge. All I can think of is pulling the level sensor out, and using a magnet on the end of a flexible stalk to try and pull pieces out. Even then, there will be non-magnetic item which could be left behind. When it's done, I'd put in some cheap dino oil and run that for a couple hundred miles as a "rinse", then change it again with your normal oil.
In the meantime, call your indy & ask for a quote... I can already tell you the vac pump (000-230-31-65) is $300-$325, and the timing device (605-070-06-45) is about $300 wholesale. Plus misc parts, gaskets, seals, & fluid. Then add about 8-10 hours labor on top of that. Wouldn't surprise me if the estimate was on the wrong side of $1500...
