I'd love to see what Calvins Quest or Fusion ports would do for your car.

Right now, there are 9 different port versions of CV1 heads you can buy. From a 235cc port up to 326cc. Rocker arms are cheap and easy to find at any drastrip if a guy thinks new is out of the budget, or if a rocker arm breaks. But the thing is the geometry of the valvetrain has proven to be right on without any alinement issues, even on a 9000 rpm engine. And if there was rocker arm issues, you know at 9000rpm a non shaft rocker arm set up would show it!!!
