if you've exhausted other methods then yes... but.. i wouldnt bother with it just yet.

i'm always in favor of polishing. porting depends on your application and how it will be done.

porting the intake wont do anything if the head remains the same.

Yeah, like blowing out the dudes rings. Unless you are going to work the bottom end as well, do not do it.
