Sounds pretty fair to me.
If you opt ro replace the chain and guides, go ahead and replace the oiler tube plastic seals as well. Inspect the cam gears for wear, replace the drive belts while they are off and go ahead and pop a new front seal in it. There are also a set of vent tubes on the injector holders right at the inside base of the valve cover, most sre rotten from heat and age, pop a new set in.
