How many heater hoses required? 444-544

I'm removing all the heat system out of my 57 pv444,hopefully tomorrow.A hot rod builder friend is going to install a aftermarket heat/ac unit under the dash.There is a fitting for a heater hose on the back of the cylinder head,1 on passenger side of the block,then the thin metal tube that goes from water to rear of engine.

I only need one hose to flow water to the heater core and one hose to return water back to block.Thanks for any and all help.

      as;

      ...but I think he needs to know the flow scheme and where to make the connections...and which hose falls away (presumably the new Heater has its own Heater Control Valve...it better!)

      tj;

      This 544 Cooling System flow diagram should clear things up (Graphic is for a B18 equipped 544, I expect even a B16 444 will be similar enough for graphic to be useful):


      (Link to Picture if I get this wrong and it doesn't embed into posting: http://www.sw-em.com/Cooling_Flow_544_B18.jpg

      Good Hunting!

        Gotcha.
        Here's an old photo of my '60 B16B.
        You can kind of see the routing. Maybe it'll help.

        The B16 does not have the pipe under the intake/exhaust manifold.
