For anyone trying to do the best they can without swapping cams, I think these are great. Without boost it definately would not be a good mod though. I would love to see someone hit 11'* with these rockers and stock cam/stock heads/m90. I am confident it can be done I just don't know how long it will take for someone to do it. The nice thing about these rockers are they help compensate for the loss in lift you get when you use stronger springs. Since with 1.9'* you really need stronger springs if you want to rev very high, you lose some lift due to the springs and you're not doing a whole lot better than you would've been with 1.8'* and stock springs. So with 1.95'* you make up that little amount.
I unfortunately don't think these rockers will be too popular, however I do feel they will give a noticable gain to those maxing out their rocker setups. We've been there and done that with the GTP and had these been available at the time it would've been a nice thing to have.
