Does the cam rotate freely in the cylinder head on its own?

264 is the max with standard pistons, so I don't see why 262 wont work.

288 will go with standard pistons as well. clearance is minimal and timing needs to be a few deg from optimum but they will go in and run well.

its also down to the lift, I did some 292 degree cams with very little lift recently for a customer with standard pistons.
