Max head is around 130 inches. The half inch nozzle will definitely add friction loss and create additional head pressure as a result. The flow charts are below in this link.

You can use this head loss calculator to get a ballpark on your total had loss. Select the Royal Exclusiv RD3 50 from the drop down.
