Your best gains are from cold air intakes, test pipes, and catback. After that you follow a path of diminishing returns - ported manifold and headers will net you something, but it's relatively costly for limited performance improvement.

I did Z1 Intakes with velocity stack upgrades, 63 mm ported throttle bodies, z1 ported upper mani, fast intentions long tube headers, fast intentions exhaust, dynoed at 334 whp, 278 wtq (and my torque band starts early thanks to the headers).

I keep a lot of dyno data and results in a shared Google Drive file, you may enjoy looking over it.
