There is a dedicated ARP stud kit for 2wd blocks, which of course is just studs/nuts.
If using a group a, no retorque after running will be necessary at all, I never have, the gasket(group a) is FIBROUS so retains an element of springiness about it which is why I like it, it also is more likely to cope with any slight imperfections on the surfaces of the head or block better than steel will.
I personally know of a 540bhp 3 door on a group a that also does track days and it really is driven hard, and it has not leaked in over 40,000 miles.
