My problem isn't rolling off the tip on the exhaust side it's getting it closer to the exhaust side... You do see that in the picture correct?...

Yep. But...like I’m saying, you are only raising the shaft, and that makes it closer to the valve/spring. If you raise the shaft AND move it away from the valve you’ll see something different.

And yes, it’s expensive to fix, but worth it.
