typically the intake manifold is "port matched" to heads that are ported.

The power gained is mostly from the heads paired with a cam

It wouldn't make sense to get ported heads unless you put a cam in it at the same time.

Not necessarily. You can make noticeable power with good ported heads on the stock cam.

Just answering your original question: ported heads, no doubt about it.
Manifold porting, matching, whatever...wont pay dividends until you've added well over 100 hp over the stock setup.
