Would You Use This Timing Cover?

The one I used on my motor was worse than that. I just cleaned it real well, roughed it up (including drilling tiny holes for anchor points), and used JB Weld. After it dried all it took was a couple minutes with a file and it was good to go. I pulled it off last year (after 4 years and ~10k miles) and looked perfect. I wouldn't hesitate to do it again.
