Should I still put antisieze on my stainless studs into heads for exhaust manifolds, from my cast manifolds to turbos and from turbos to downpipes. All are stainless studs and think copper nuts and stainless washers.
Kit instructions don't say anything about antisieze but figured might be good idea? Or can it let parts loosen up when you don't want them to?

I put hi temp antiseze on my arp header studs. Never had any problems with them backing out. I also think it wouldn't hurt to put it on the "hot" side turbo hardware as well.

Absolutely do it. Stainless can react with aluminum and anti-seize will help prevent this.

I agree. Use anti-seize.

General rule of thumb: Use anti seize on:
Stainless to stainless connections,
Stainless to aluminum connections,
Aluminum to aluminum connections.

Basically anytime you are mating two non-ferrous materials you have the potential of galling/seizing and should use anti seize.

Also use it on bolts and connections that come into contact with high heat sources.

Absolutely.

Yes to all of the above! "Like" or same material fasteners/connections always want to gall to each other if it a dry fit. ie: Stainless to stainless or any AN fittings should have at least a small amount of some lubricant on the threads.
