yes Im at 11.0:1 comp , .600 nett lift . Dont forget Im at 505ci so a few more cubes . But most would say Im leaving HP on the table by not using a solid roller . I shift @ 6500 trap 6700ish .
Same bottom end with Source CNC heads and 4150 carb went 10.50@126ish . So that was about what i expected to gain .25 ET . Expensive upgrade though . That will give you an idea of your potential gains .
