Which gaskets with 1/2" studs

I've got a 6.0 iron block with 4.030 bore and 1/2" studs. What GM mls gaskets can i use? I have a set of gm part number 12610046 and they do not clear these studs. i have to thread each stud through the gasket and then hammer them through to the threaded portion (of the block) then go about tightening the studs. I was told this is normal, but it damn sure doesnt seem right.

i'm pretty sure the ls9 MLS gaskets fit right over 1/2" head studs.

I have close to the same setup and I used ls9 gaskets and they were big enough to slide right over the 1/2 head studs

The LS9 engine has 12mm head studs so the holes in the gasket are slightly larger. Also put the gasket on the block, then thread the studs into the block.
