Valve seals tore on break in

Hey all, I just broke in my 440 which went great except for it tore the tops off 3 valve seals….so far. I had some small pieces laying in the heads. I’m not worried about the blue rubber, I am worried about these tension springs/bands that are now riding on my valves and their potential to break and get into the crank case.

What should I do?
