1/2" is the biggest they come on a SBF. I've never seen ayone try to go bigger. I never TQ less than 115 on the long studs, 125 if its a real long stud.
I wonder if ARP makes a Custome AGE material head stud for a SBF like they do for the diesel heads. I'm building a 6.0 with them right now. $1,200 lol.

ARP does have them in different materials sometimes, just have to call them with lengths you need and see if they can find something on shelf. I have ARP 2000 studs on top of mine, just had to stack a couple washers to make them work cause they were a little too long.

Yeah they dont make a set for my heads but I was able to meaeure what I needed and order them individually. Worked out great!

ARP 9/16 with brand new Bennett Highports. Flatout gaskets wire and receiver groove. I will say 20lb should hold on SBF but like said 125 with moly

So the block side is 1/2" and the heads are opened up to 9/16" ?

You dont really think its a undercut stud? Come on now its all 9/16 even the block. I still only torque 130 they will handle lot more but i will never have to worry about bent studs again. A1 technology makes H11 sbf head studs but i was told they are going out of business
