The ARP kit is fairly inexpensive, and it is certainly convenient to unscrew the studs for head removal/installation.

The head bolts are the same. I believe the early NA studs have been deprecated. I am aware of only one available part number currently available.
That said, I highly recommend the ARP head studs, as they have an Allen key for easier installation and removal, as Rasta mentioned. They also provide better and more consistent clamping force, which is important on forced induction applications, particularly when increasing boost beyond OEM levels. Unlike the OEM bolts, they are reusable.
