Here's a couple of suggestions. I have my truck grounded with this and the grounds have no paint or anything hindering their grounding abilities;
1. Battery to frame
2, The starter is also grounded to the frame.
3. A ground strap off of each cylinder head.
4. Cab to frame
5. Bed to frame.
I use inch wide braided grounding straps. While the grounds may not be your issue, I suspect that one ground you have coming off the valve cover really isn't doing much. The valve cover has a gasket under it and it appears the valve cover is also painted.
