Case through bolts are not head studs. Stock through bolts are fine and ARP headstuds are not the best choice IMO.

2nd that.
OEM case through bolts and 993 dilavar or supertech for the head studs. ARPs don't seem to be "thermaly expansive" for the aircooled motors and some have had issues with studs pulling out of the. If you're worried about case main migration under heavy load, have the case shuffled pinned.
