The Performer 289 (what is now the Performer Plus)is not an aluminum version of the stock 4V. I've got one sitting on the shelf, and I can tell you it sits higher than the cast iron 4V intake. Those cast iron intakes have very small plenums.
Personally, I don't see a reason to switch until you find a pair of good heads. The Edelbrock will work just fine, and I don't think you'll actually notice a difference if you switch to the Weiand. Just because they claim it made 14 more hp on the same engine doesn't mean it'll make 14hp on every engine. You'd probably only see a slight difference up above 4000rpm, and how often do you plan on spending up at that rpm range?
