It is a lot of work but we do it right on the engine with a lifter shimmed solid at the preload we are using. Very time consuming but about as accurate as you can get per application. No, it's just for testing / comparing / plotting rocker ratios. Your way is the best if you want to include any "outside influences". Fastest 300

That tool would be handy to insure a full set of rockers with the same values. It may take several sets to make up one well matched one. (Been there - Done that) Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

They should work perfectly well on any flat tappet cam and will even work on a small street type roller cam. Same thing goes for the Isky nodular arms and maybe even the Crane iron rocker arms. I switched over to the RAS stainless arms a few years ago and that is almost all I use anymore for moderate performance engines. For the really killer motors you have to step up even more to T&D or Jesel. It all depends on how much power you want to make and how deep your wallet is. Your question was so vague that nobody can answer it so we are all just guessing what you ment by "race rockers". You aren't going to find original MW rocker arms on very many race cars that go rounds at NHRA events, but you might find them on a local bracket racer.

I realize that high horsepower high $ racer would never resort to these kind of rockers. Just have some laying around and was wandering if anyone ever used them with success in a bracket car of circa 6 to 700 horsepower ! E.

Maybe Indy EZ heads with a big flat tappet cam would get you there but I think you would be scrubbing the valve tips pretty hard. Not really the smartest way to build a motor.
