Sure. Head comes from just velocity.
Figure out how high the water would have to be at a standing start to end up falling that fast, in free air (actually, in vacuum) at one gravity. That's the head. (Alternatively, imagine a frictionless curved surface turned the water from horizontal flow through ninety degrees to an upward vertical flow of the same velocity and figure out how high it fountains.)
h = v^2 / 2g where g ~= 9.81 m/sec^2
Volume flow is volume flow.
