i guess coolant/oil or not doesn't really matter - either way you're in a headgasket job. and like we've already said - you can plan your repair out way ahead of time.
your timing components are 10 years old - replace those and that labor is "free" since they have to be removed for the headgasket anyway.
new OEM gaskets, resurface the heads, adjust valves if required, OEM or AISIN timing kit, new thermostat, radiator hoses, plugs, wires, PCV and you're good for another 100,000 miles.
