Header studs or bolts?

So Im putting in a new set of TTI long tube headers, and have had people recommending to put studs all around in place of the bolts. Those of you with headers, whats your thoughts on this? Bolts vs studs? I have aluminum heads so anti-seize on whatever I use will be a good idea Im sure. Also, for the end holes that go through the water jackets, whats a good recommendation for a thread sealant? There are so many out there, its good to hear what has actually worked well for people.
