Bank one and Bank 2 pre cat?

OK....got a bank 2 failure code.....is that the one closest to the front of the car or the harder one that I have to rip the top of the engine apart to get to?

taking off the valve covers, intake, etc isnt required to take off the exhaust manifolds. Bank 2 is the one located by the radiator. Thats the easier of the two.
