Stagmiere racing recommended me this quick fix to the very annoying valve tick and it worked for me. They suggested to get rid of the 5w 20 oil which is way to thin to begin with and told me to use 5w 50 made by motorcraft. Apparently ford decicded that this oil is best to be used in all there new svt products. And yes it worked!!! The noise is gone.... I'm not sure if it will work for everyone but it did for me. Good luck.
