It may be within spec for a factory organic head gasket, but under no circumstances should you purposely attempt to install a metal head gasket without machining both the head and block surfaces. There are countless threads and posts about not doing this.
You can try to retorque, but I don't see it helping. And I've reused ARP head studs before. I think several others have and I haven't heard of anyone having problems in doing so.
At this point, I'd cut my losses and put an organic head gasket back on there. It will be adequate for your power goals.
