A gas burner assembly for a poultry house heater having a head that is fabricated from a metal stamping process. The gas burner has a venturi tube which extends between a burner orifice and a burner head. The burner head is manufactured from a top plate and a bottom plate. The top and bottom plates define about forty upper half and lower half burner ports wherein the lower half ports of the bottom plate are in registry with the upper half ports in the top plate to define the ports for the gas burner. The interior of the head is shaped to form a chamber around the junction with the venturi tube having a height greater than said ports, and the interior surface of the head is smooth and free of sharp edges. The top and bottom plates are mechanically connected by a series of tabs and slots formed on the top and bottom plates.
