It's hard to port and polish plastic, but not impossible. The SAM school tried it and only gained about 3 hp, and that was after using about $400 worth of Devcon plastic filler. The problem is the intake has very thin walls. The Holley aluminum intake can be ported and polished, but it has fit and heat soak problems. Looks nice though.
