Alright, more fartin around and not much progress, but I found a stud that will work for the first 3. It is this one here:

I ordered 3 and got them installed used an ARP 12 point nut & washer.
Original stud on the left, Allen in the middle and the ARP on the right. Hope that helps.
And Rusty, I’ll be working on the fuel system this weekend. I got my Aeromotive in tank fuel pump I have to install and run some 1/2” feed & return lines.
