If you're on a budget I would consider keeping the factory HSV headers and factory rockers. If your were after a set of rockers Crane or Yella Terra would have something to suit.

You can go larger extractors however I would recommend you stick to what you already have, considering the proposed mods

Given the factory manifold that's in place I would stick with a stage 2 kit
