If you've already calculated that you need 3" round ports at 5.5" long, buy pre-made flared plastic ports and mount them.  No need to change your design.

Polyfill will increase the effective enclosure volume.  about 1 lb per 1 cuft will incerase the effective volume by 10% (0.1 cuft).  Yes, you must take this into consideration.
