I better get this subject turned around off of snowmobiling (Rose's favorite subject) and back to the heads..
I guess from what I'm gathering I'm going to need new head bolts? Likely ARP. It's what I have now...
I can't see from the pictures but I think you only need one extra long bolt per side. If you look at the top row of bolts between 1-3 and 5-7 intake ports, where the oil feed hole comes up...those bolts on OE heads has one short one. It should be the front bolt on the drivers side and the rear bolt on the passenger side. Those are shorter on OE heads but I believe the length on those heads.
I use head studs, but I have to pull the master cylinder to get the drivers side head off over the studs. My studs are probably from the late 80's or early 90's so they don't have the hex in the top of them. If you get studs with the hex in the top of them, you can just unscrew the long studs and take the head off without any hassle.
