What are these for?

I can't get these studs out of my old block, and they look important. The B302 didn't come with them, so I guess I need to call up Brenspeed and see if I can get a few. Don't know what they do though, as I can't remember from my disassembly lol.
i see you are missing a pulley which i am guessing is what the stud on the right is for (although mine looks to be set on by a bolt, not a stud) and the stud on the left.... ehh, beats me cuz again, mine is a bolt and not a stud... let me get u a pic real quick
Well this was taken in the process of disassembly of my blown motor. So I have the pulley, if that is what went on there hehe. But to be honest I don't remember anything on that one. I remember the alternator sat next to it on a threaded stud . . .backwards. But the stud(s) in question aren't threaded on the external end. They have a 7mm hex on them.
Ya I know exactly what you are saying. Its tough for me to get a good picture because of the intake, but honestly, I'm not seeing anything closely relating to a non-threaded stud sticking out... I dont know what else it could be
