You would have to experiment or gets some advanced engine software, you would have to think the original engineers did a fairly decent job to start with. You could buy a after market cam with a wider lobe separation angle or LDA.

Not something I want to focus on, right now.
You can epoxy the manifold for peanuts but again, you may dump a huge amount of high RPM flow for tiny gains on the low end. Again the original engineers probably have your engine dialed in pretty well already.
