Sure, it would be nice to replace the AOS; water pump, coils and plugs, oil pressure sending unit and sensor, fuel pressure regulator, crankshaft position sensor, positive crankcase ventilation conduits, etc., etc. Then I could drive to the poorhouse in style! After I make a decision on the cam chains I think I'm going to draw the line there. It's getting close to a year since I've driven my baby. I'm jonesing to get it back on the road.

Of all the stuff you mention I would only consider changing the AOS simply because it is a lot easier to do with the engine out. Water pump, coils, plugs, CPS etc can be changed when and if necessary with the engine in the car. Chains should be fine.
