After figuring out that I can tighten my header bolts with an allen wrench, I borrowed one from a friend today and tightened the bolt in question.

After tightening it and starting the car, much to my dismay, I find that the leak is still present and coming from aobve the header (not from the bolt). This clearly means that the Mr. Gasket Ultra Seal gasket is shot as a result of the drastically loose bolt!!!

How much do shops charge to change header gaskets? Bear in mind that it is the passenger side of an L98... it is burried under a million things.
