Do you know what your IDC is? You may need to upgrade injectors if you add any mods. That said, you've improved air flow through the engine with bigger throttle body, ported blower, and headers. I personally think you either need to port your heads or upgrade them. New valve springs and a trunnion upgrade would make sense when you port your heads.
