Have you determined that the guides have not been replaced? Maybe you should take the front of the engine apart before ordering the parts. If you find metal-backed guides on BOTH banks of the engine, they're done already. Some say ALL the engines may have metal-backed on one side anyway, so confirm both sides.
It's going to take more than a day. You have no experience with this engine (I don't think) so it's going to take a few days.
Unless you've got 250,000 miles or more on the thing don't even think about replacing the timing chain itself. It will stretch a bit over time, but will last the life of the engine (I don't think anybody here ever heard of one breaking without some traumatic outside influence - broken guides, and I even doubt that).
Absolutely DO replace the oil pump chain and sprockets.
Good luck,Glenn
