Turbo Qs

[super white alero1]

This quote explains better than me
The hydraulic lifter comprises a cam follower that is moved up and down by contact with the cam profile, and an inner bore into which the valve lifter is closely fitted and retained by a spring clip. The valve lifter, in turn, is a cup closed at the top by a freely moving cylindrical plug that has a socket at the top to fit the lower end of the pushrod.

I would've assume that Ion would have used followers instead of the stock rotator. They periodically show up in JBO classified.

The benefit of such a setup is not noticeable for power but reliability since rotators don't react fast enough depending on what your redline is. Followers uses bearings and therefore response faster.

The reason most people don't do this is because its worthless unless you plan to do circle track, road course , or endurance.

Does it make sense why I got all those suspension/brake crap now.
