Depending on how warped the brass is, you may be able to salvage. Almost certainly, the threads have been stripped out of the group body when the bolts were pulled upwards by the ice expanding. If you can cut new threads, or if they aren't too damaged and can be fixed by a tap set, then you may be able to get away with keeping the group body. You can also go to a car service center and get what is called Recoil thread inserts, or order them online. This is what service centers use on your car when threads in the engine head or block get damaged. If the brass is too warped you will have to blaze it to get it hot enough to reshape. If you have the tools, and the time, you can do this.
