I was wrong on that. They do have grinders capable of grinding a sphere.
While most of their lifters seem to work, that is the WRONG way to do it.
With a sphere, you have single POINT contact instead of flat line contact resulting in much higher unit pressure.
Isky found out early on that a spherical surface had very poor wear characteristics. With a race cam they did not last to the main event.
