Get a copper heater core, not an aluminum (usually aftermarket) one. If you can just hook the hoses together temporarily and wait a while, I would price a genuine GM/ AC Delco copper core from one of the online vendors. If it is not too much, I would go with OEM. This is one of those PITA jobs you don't want to do again if you don't have to, especially if you have A/C.
