IndexError: tuple index out of range

I'am trying to select some values from two tables, using dictionnary, the code is this :

import arcpy  
from math import degrees, atan2

arcpy.env.workspace = "D:/Users/saadiya/Documents/ArcGIS/Default1.gdb"
arcpy.env.overwriteOutput = True
workspace = "C:/Saadia/SAFTOP/Parcelle et rivrains/simulation arcgis"


from time import strftime  

print "Start script: " + strftime("%Y-%m-%d %H:%M:%S")  


sourceFC = "Join_Output_15"

sourceFieldsList = ["RefName", "RefName_NW", "RefName_N", "RefName_NE", "RefName_E", "RefName_W", "RefName_S", "RefName_SE","RefName_SW"]
                       #0            1           2             3            4             5             6             7            8             
# Use list comprehension to build a dictionary from a da SearchCursor  
valueDict = {r[0]:(r[1:]) for r in arcpy.da.SearchCursor(sourceFC, sourceFieldsList)}  

updateFC = "t1" 

updateFieldsList = ["src_RefName", "nbr_RefName", "Orientation","North", "South", "East", "West"]
                        #0               1               2         3         4       5       6 
with arcpy.da.UpdateCursor(updateFC, updateFieldsList) as updateRows:  
    for updateRow in updateRows:  
        # store the src_RefName and nbr_RefName value of the row in a pair of keyValue variables  
        keyValue1 = updateRow[0]  
        #keyValue2 = updateRow[1]  
         # verify that the keyValues are in the Dictionary  
        if keyValue1 in valueDict :
            # transfer the value stored under the keyValues from the dictionary to the updated field.  
            if  (updateRow[2]== "North" and updateRow[1] != valueDict[keyValue1][1] and updateRow[1] != valueDict[keyValue1][2] and updateRow[1] != valueDict[keyValue1][3]) :
                updateRow[3] = updateRow[1]
                updateRows.updateRow(updateRow)
            elif  (updateRow[2] == "East" and updateRow[1] != valueDict[keyValue1][4]):
                updateRow[5] = updateRow[1]
                updateRows.updateRow(updateRow)
            elif  (updateRow[2] == "West" and updateRow[1] != valueDict[keyValue1][5]):
                updateRow[6] = updateRow[1]
                updateRows.updateRow(updateRow)
            elif  (updateRow[2] == "South" and updateRow[1] != valueDict[keyValue1][6] and updateRow[1] != valueDict[keyValue1][7] and updateRow[1] != valueDict[keyValue1][8])
                updateRow[4] = updateRow[1]
                updateRows.updateRow(updateRow)



print "Finished script: " + strftime("%Y-%m-%d %H:%M:%S")

but i get this error :

Traceback (most recent call last):
