The head studs are certainly a good place to start. The early dilavar studs were prone to snapping. I recommend the 993 TwinTurbo head studs over all others, but after looking at the prices for these things, I can't believe how much they have gone up! If you can find the 993 TT studs for the same price as the ARP studs, I would pick the 993TT studs, imho.
I would also replace the rod bolts with a set of ARP's, while you're in there. These two areas (head studs and rod bolts) will give you piece of mind.
Of course, if you're replacing rod bolts, you might as well replace the rod and main bearings too. Feeling that slippery slope under your feet yet?
