The timing slot for both camshafts is below the axis of the camshaft and parallel to the head surface that mates with the valve cover. Don't rely on the camshaft lobe for reference. It is not accurate enough. The camshaft sensor "nub" is identified below with the blue arrow.

If the passenger side camshaft is in the wrong position (usually about 30 degrees off) then you can move it to the correct position once the camshaft sprocket retaining bolt is loosened. Do you have the OTC-6488 timing tool kit?
