Ported Maf ends

Just leave the stocker in there and leave the screen in, its fine for alot of HP.
The MAF also measures how much air is going past it and this info is relayed to the PCM and it figures out how much fuel to spray from injector. The computer tune can adjust this info and eventually get it re calibrated by "hands on" tuning from a skilled tuner and lots of time if using a ported MAF or MAF ends but a mail order tune is NOT gonne be exact the first time.
As mentioned, the other things are restricting flow far greater than the restrictions in the MAF so there is really no reason to use the MAF ends until you have a serious set up with lots of these restrictions removed, a good set of heads, big cam, big headers, etc, that require more flow than the stock MAF can handle (450+ RWHP) AND have your own tuning equipment that you are very good at using.
