Intake upgrade?

So I have a 340 , .030 over , 10.5/1 , .525 solid flat Cam , eddy heads with 1.6 RRs , Victor intake , 750 Brawler , 4 speed and 4.56s. It's mainly driven on the street and have some fun. I am planning on building another 340 in a year or 2 that will be more aggressive. I have an opportunity to purchase a Super Victor for a good price (new). 1) if I port matched it and bolted it on my current setup , would it give me any performance gains at all or would it have adverse effects? 2) would it be a better application for the new motor I plan on building or is my basic Victor good enough?
