"The OEM headbolts with necked-down shanks are pretty hard to beat."

I wouldn't argue with that. But I went to studs for a very specific reason... the ability to safely seal the threads of the number 2 (left side, center) head bolt hole. I was leaking oil into the water, apparently due to a crack in that hole, which carries full lube pressure when the engine is running. No way to safely seal it if using a head bolt, since you'd be doing it blind; put just a tiny bit too much sealer in there and you've not only sealed the threads, you've plugged off the oil supply to the head.
