I just drained my oil and it was milky, I know the 3.4 is bad for head gasket leaks. My question is should I change the intake and head gaskets? This engine came from a wreckers and has 120,000 km on it, so I don't know if they have been changed already. If it was a head gasket wouldn't I have white smoke coming out the tailpipe? if it was a intake gasket would coolant leak into the oil?. I'm thinking about doing the whole top end just for peace of mind.

It's relatively rare for a head gasket to go on the 3400 or 3800. I've only seen a handful that actually went bad in the many years I've been floating around this forum. Odds are it's a LIM gasket failure. I'd just do the LIM gasket unless you have a real reason to go after the head gaskets.
Protip: If you don't know what you're doing, don't do it.
