Hopefully you already did this, but make sure the stud holes in the block are completely dry. When I recently changed my head gaskets, I cleaned out those holes with brake cleaner and left a few drops in the holes. When I put the heads back on and screwed the studs in, it forced the fluid out and would've compromised the gasket installation. Good thing I noticed. I took it apart again, cleaned out the holes meticulously with air and a rag, used new gaskets, and reinstalled. Of course, I used a bit of ARP lube on each stud and nut.
