I tried your suggestion and took the isosurface out of the union it 
belonged to:

isosurface
{
	function {fFinal(fInpX(x,y,z),fInpY(x,y,z),fInpZ(x,y,z))}
	threshold	0
	accuracy	0.001
	contained_by
	{
		box {0,2}
	}
	max_gradient	50	// was 20000
	all_intersections
	max_trace 3
}

But it did not solve the problem. I still get the jagged looking artifacts.
