If you can still turn that VX in and get out of the deal, Corey, do it. New rings may fix the problem, but you might find much bigger problems when they open it up. This just happened to a buddy of mine this summer... he was going to replace the head gasket on his GTA to finally fix an oil leak, but they found a groove in one of the cylinders when they opened up the engine. Bad news. His $1000 gasket job turned into a $3500 new-bottom-and-rebuild job.
