Re: what would you do......

I would do nothing.

I think part of the deal with the ARP studs is you need to re-snug them not
to long after first installing them.  They don't stretch like the ones
specified, and will loosen while running as the head grows and shrinks with
temperature.

Smokey Yunik says on arp-bolts.com: "If you can't stretch the bolt enough,
it can still fatigue, lose torque or get loose."

I think the main advantage of using ARP studs is the reusability. People who
take the engine apart all the time would use these...
