This has been a long standing debate...
The OS plugs have a different taper at the end. THey don't seal tightly in a Nova head button. If you crank on the plug when you install it the head button will distort the head button and Nova plugs (or any other manufacture) will not seal properly. SO no it will not destroy the engine, but it can distroy the head button.
