How longer and tight bore effects shooting?

Hey guys.

I'm looking to upgrade my new gun and I figure inner barrel should be a good place to start.

Could anyone tell me the effect of long vs short inner barrel?
Example, m4(363mm) vs m16(509mm)

Another decision would be tight bore. What effect does it play?
Difference between 6.03 or 6.01.

I understand the length and port ratio but if you know a place were I could gather more knowledge on inner barrel please let me know!
