Finger tight studs in block with RTV on the threads and a light wipe of antisieze compound on the stud shank allows the studs to be removed before the head during the next head gasket replacement, making the head removal and cleaning of the deck a snap..

If RTV is applied every time the stud is screwed in, it will build up in the bottom of the hole over time unless someone is smart enough to clean it out and there are not many people like that. Once there is a buildup in the bottom of the hole, screwing the stud in even to the end of the thread might break out the bottom of the hole.
Unless the hole is already broken out, I don't use silicone on the studs. A drop of oil or a touch of antisieze is the limit.
