How do I analyize blocks that are touching each other?

I have 10 block groups that I want to do a test on.  I've added a productivity value to each of these block groups just for a testing.  No the record I would not do productivity on block groups.  For the productivity value I have created a 1-5 range.  1 being under productive and 5 being overly productive.   What I want to do is find where blocks that are overly productive (5) touch an under productive block (1).  What I am trying to do is find places where we have great productivity next to an area that is under productive so that we can do further research to see if these might be area's of oppurtinity to grow the productive area and shrink the under productive area. 

Can someone walk me through how I would do this?  This is very small scale as a test but I will need to do this on a much large scale for over 1000 files.  I would first like to figure out if it can be done and if so what is the best tool to use in ArcGIS.
