I think, personally, ARP's track record speaks for itself.
I ran ARP studs on my smallblock, with LOTS of compression, and LOTS AND LOTS of nitrous, and never had any real issue.
I've never had a great deal of issue with the ARP studs, but my thoughts are if you're replacing a failed component with one of the same design (bolts/gaskets) is only asking for a repeated failure.
I think though when people are gonna abuse the hell out of a truck, the best thing to do is try to aid in the vehicle LIVING through the abuse, and I think the ARP studs are definitely a step in the right direction.
