Changed Rockers and Cam Shafts - 1989 420SEL

I changed all of my rockers and both cam shafts on my 1989 420 SEL and it is idling very rough both hot and cold. It was never like this before the changes. Tried to adjust the valves with shims but still a ticking from some, I don't have one of those fancy go/no-go guages. Any recommendations or possible problem analysis?
