Increase length of arrows in vectorfieldplot3d

Hi,
     Just using vectorfieldplot3d for the first time (plotting
computed normals of a surface f(x,y) as it happens..).  I can't seem
to increase the length of the vectors, even if I multiply the vectors
by 1000!  Using Mathematica 6.0.2.0.  Example:

VectorFieldPlot3D[
 1000*nrmDblSinClamp[x, y, boxXext, boxYext, 2, 1, 0.0, 20.0],
 {x, boxXext[[1]], boxXext[[2]]},
 {y, boxYext[[1]], boxYext[[2]]},
 {z, -2, 2},
 Axes -> True, AxesLabel -> {X, Y, Z}, VectorHeads -> True]
