I think you're kidding yourself if you want to run a .700+ lift solid roller on the street and not replace valvesprings. This is why those "street car classes" are a joke, guys running cams bigger than this and having to replace valve springs during the event... ya real street car
Have you ever ran a street car with 700 lift or more? Ive done several without an issue, and that includes hemi's. Spintron technology has helped valvetrain advance a lot in last 5-8 years.
