You don't "need" to replace both head gaskets if only one is faulty, however, most commonly, when one side fails, the other side isn't far behind. Most shops will recommend both be done at the same time, while they are in there. No sense in doing one side only to have the other side fail shortly after and then have to go through all that labor all over again. It's like preventative maintenance. While you're in there, you might as well do it.
