^^^ditto...the bridge can give far and away more power...but drivability suffers...do a search and weigh the qualities of the two.

Please take my advice from my own series 5 ported N/A rebuild (that I built and ported). You CAN have too large of a streetport with a 6-port and airflow suffers through the secondary runners up to where it reaches the block (when it "separates" to make room for the auxillary ports. It's the rods that turn the auxillaries that disrupt airflow. Also, I currently leave my auxillaries wired open (I have no accessories -->airpump, etc) and I have a decent midrange but there's a power peak from 7k - 8.5k. Not as streetable as I'd like because my powerband basically feels like it's from 6k - 8.5k. Please take my advice and go with a 4-port N/A setup and do a large streetport. The results will be soo much better. Either use just 4-port secondary plates, or use all 3 plates from a 4-port.
I guess one more option would just be after porting all 6-ports, to "pin" the auxillaries open in the block and fabricate a new intake manifold setup with MUCH shorter runners (AKA: Kahren's car). Basically what I'm getting at is that the 6-port intake manifold setup sucks, except for the VDI of course. This is just from my experience and opinion however. You will have more gains from a much shorter manifold and with larger runners. I would not suggest a bridgeport in my opinion.

You do not want to drive a bridgeport on the street.

There is nothing wrong with a bridgeport for the street, you just find yourself rolling in neutral quite often, you could go for a big stage that will give you a nice slow pulse and wont take any of the drivability away and will not wear as quick as a bridgeport.
my 2 cents

bp the aux ports and keep the sleeves.
