What is the difference or advantage of the N1 timing chain tensioner vs the normal one?

It stronger than the normal tensioner. So it won't die if you keep reving to like 9k. The normal tensioner can do it but it can't take it for a long time before it starts to fail from the stress.

Thank you

actually the face is shaved to go a little deeper in the head. also the bleed hole is blocked off. rest is the same....
