Correct Hardware material for exhaust system?

Again, apologise if this has been covered, just can't find it.

About to mount my stainless headers, turbo etc, should I use stainless nuts on the engine studs? Stainless bolts and nuts on the turbo? It seems the stock ones are mild steel and they may be that way for a reason as they expand and contract at the same rate as the studs?

One more question, as nylock will just cook as soon as it gets hot should I use two nuts or some kind of high temp loctite?

cheers everyone!
