Those are very common problems with alternators and short water pumps. If heads are aftermarket or Vortec with a raised valve cover "rails", even stock height covers will interfere. I actually extended my upper bracket by a couple inches and used a longer belt. It's tight, but I can remove the belt.
I'm not sure why your alternator pulley doesn't line up with the crank pulley. Here's my setup using a lower cast bracket that mounts to the head. I know your heads don't have bolt holes, but maybe this picture will help someone else.
