Sealing studs can be a challenge - BOLTS will seal with the ARP stuff, but NOT studs. Like Tom G. said, Leak Lock works, but it is very tough to get the studs out afterward, as it is a hardening type of sealant. I started using snowmobile case sealant ThreeBond #1211 (silicone based) with very good results. Take the studs out one at a time, clean, apply new sealant, then retorque.
