small block belt arrangement?

Hi, I am puting together a 340 and need to know the orientation of the belts. I have power steering, aluminum water pump,2-groove crank pulley, single groove water pump pulley.does the power steering belt go on the rear groove of crank pulley(closest to engine)? looks like it to me, but all of the water pump pulleys I have are the same( 2 1/8 deep) which also lines up with the front groove as the P.S. does. do I just need a deeper W.P. pulley(would need a pulley about 3/4 deeper to line up with rear groove)sound right?
