Im pretty sure they would work better but the problem is having the clearance to tighten them. I know with my 1 3/4" primaries...its REALLY hard to get in there. I imagine studs would make it even worse.
i posted a little further up that i use ARP Header studs instead of bolts, they came with regular washers but i use split lock washers instead. They are always tight. They are great with my shorties enought room to move htem around and it makes lining them and gasket super easy.
