yep i'm using them here's the graphs in the wife's 99 formula. these are the VHP/Crane 1.89 accelerated lift rockers. do not pay attenion to the torque peak as there was a spike at the beginning of the run. this was on a stock cam also.

and here's a recent dyno #14(1/20/05). even more gain over time.so using dyno 9 before rockers and dyno 14, about 8 months later, you see a 17 rwhp gain the dyno 11 was about 2 weeks later and 250 miles on them.
