We just put this kit on my racecar. Why? Well, all of the aftermarket rockers are HEAVY, with most of the increase in mass above the valve. This is the WRONG side to have it on if you're planning on running high RPMs for extended periods of time, like I will (20 minute races, all above 3500RPM).
So, now we've got very lightweight rockers (stock) but with excellent bearings.
Yes, they use C-clips on each end to hold them in. Be careful when installing them. The needle bearings are held into the race with grease, so makesure not to drop them (unless you feel like trying to find a few dozen bearings on your garage floor).
Also, after you soak them in oil for a while, make sure that they turn freely. The first one that we installed had a sticking point. Basically, when you'd try to turn it, it would stick slightly. We had to disassemble and reassemble to get it working properly. It was probably just a piece of dust or something we did while pressing it in.

We used a socket that was the correct size to press them out. Put a large socket on one side to hold the arm, put a small socket on the other to push on the old trunion. Make sure to have a pan below for when the few thousand needle bearings fall out.
You're reallys supposed to use a hydraulic press for it. But, we used a large bench vise. Make sure you put something smooth on the face of the vise (we used some aluminum).
When you are pressing them out, no real magic. But, when you are pressing the new ones in, you have to make sure not to go too far. Press it in until you can just see the groove for the C-clip. Don't got too far - it's easier to press in more, it's harder to press out.

You might be waiting a few years. After all, the only "good" feedback you'll hear is, "Well, nothing is happening so far."
Can't blame you for waiting for a new product to prove itself, though.
However, these have been in use for over 2 years in Nascar in their LS-engine-only series.
