A gas burner head assembly characterized by a flame-leading pipe strategically positioned between a burning plate and an igniter to provide a climbing path for the flame. The igniter is a part of a standard gas oven and has a fixed height. The burning plate rests on top of a housing that confines a gas-air mixing chamber. The upper open end of the flame-leading pipe is secured on an upper rim of a peripheral wall of the housing. The lower open end of the flame-leading pipe is aligned to the igniter and the main gas nozzle of a valve module mounted on the oven body. By leading the ignited flame to climb from a lower level located by the igniter to a higher level positioned by the burning plate, the gas burner head effectively eliminates the undesirable ignition obstruction while accommodating the standard gas oven valve assembly and igniter.
