that really depends on the limiting factor of the motor. if it has a long stroke or a very undersquare bore/stroke ratio, then it wasn't really designed to rev that much.
two things you have to think about. the engines ability to breathe at higher revs, and the engines ability to stay ogether at high revs 
would 11:1 or 12:1 not be a little too high for even 98 octane?
studs are good because they are usually made to high standards, and you get more reliable clamping force, and saves wear on block threads etc. they are always good, but not always necessary. don't rods have studs anyway?
i would guees that mains would be fine, but new rod bolts and head studs might be a good idea if you are really looking to rev the thing.
head gasket? depends on the compression and if you have pinging or not. detonation is the real head gasket killer imo. gaskets like ACL Monotorque are pretty good quality, but if you are really worried, get a copper gasket.
power? no idea. what rev range are you after?
