Make sure you put plans in to pull things back apart to retorque the ARP studs at the proper intervals. I've seen them lose torque overnight on a motor build. They have specific instructions about retorquing after a certain number of miles or warmup cycles (i forget exactly what it is) which on a subaru means pulling the valve covers and the cams to get to them.

This is why the OEM bolts are still preferred by many engine builders around my area. They are torque to yield bolts that stretch when torqued in the proper sequence. As the head gaskets settle the bolts stay tight because of the stretch in them.
