If you're familiar with port shape, yes. But it might be hard to tell with a minor port job.

You can also tell by its idle.

no. not necessarily. i've built streetports that have idled like stock and i've built streetports that have idled like mild bridges. idle is not a measuring stick. you tell by looking on disassembly (some don't smooth out runners ), but feeling around might work, too.

you can't really see the ports with the LIM on the block, it would have to be removed and then yes, a real ported motor would be easy to spot.

bridge generally makes more power but the power range is slightly higher and if it's naturally aspirated you will need a custom intake manifold to utilize it.
