I have them, and so does Bad as L. I am using them successfully, I believe he had problems. They were put in on a completely new motor so it is impossible to tell you the gains if any. Perhaps Dale will chime in.

The problems I had with them might not have been the rockers fault. When I had my heads done one of the things we did was move the keepers up on the valve stem and cut the valve pockets and installed a set of after market LS-1 chevy valve springs. I wanted to run big boost and it takes a big spring to handle that. Well it turns out that the guy who did my head set up had gotten a calibration spring for his spring tester from Crower and it was all wrong so when he set up my valve springs he did it to what he thought was the right specs but I ended up with something like 145lb of seat pressure. That is over twice what a stock motor has and anyway the rocker adjusters couldnt take the pressure and started chewing themselves up. The intake valves had quite a bit more spring pressure than the exhaust so the intake rocker adjusters showed the wear, the exhuasts were fine.
I got another set of rockers from SSS free of charge, they had changed the adjuster design and figured I would be the guy to test them . I also put a more realistic valve spring in at the same time.

Funny thing is when I went to the smaller crower spring with only 95lbs of seat pressure......after a short time the tops of the valve stems showed there were signs of valve train seperation at 23 lbs of boost.
So I think the engine needs a lot of spring at high boost, just not as much as I originally started out with.
Also the best feature of the rockers is the solid lifter, there is no lifter pump up even if you do float the valves and when I ran my truck it felt like it wanted to rev forever. I could see having shift points over 6000 rpm easily with good springs.

PS...I just bought a set of 4V heads and am changing the way I'm doing some things, so the rockers are for sale
