I would guess if he is asking this question he is not wanting to "build" the engine any.
The job is mostly taking stuff off and putting all back on in reverse order. Where you have to be carefull is torquing the bolts to the right amount and in the right order and putting gaskets on correctly and adding some sealer in the right places.
It's not really that hard of a job but you just have to be willing to jump in, do it, watch what your going and ask alot of questions if you don't know.
Probably your biggest problem area on a V6 would be the exhaust manifolds. If you try to take the manifolds off the heads it's easy to break the bolts since they rust in. You could leave them on and slit them at the Y pipe but can even have problems there is they are really rusty.
Just giving you some facts so you can think about it. If all goes well it's not bad, just takes time.
But if things are rusting they tend to break and then you have to deal with a slew of new problems and $$$.
If your willing to have the car down for a while I'm sure you could post here and get answers to all your questions as you work you way through it.
