I've ported intakes for guys that race in classes that you are only allowed to (blend) into the port 1 inch and thrust me that takes some time. It sounds like you are not limited like this so trust me its worth doing. That intake stinks if untouched and the good old Victor beats it hands-down. One other thing to check out on the Super Victor. It sits MUCH higher and you may have to run valve cover spacers with some valve covers. Even with some grinding I had to so if the engine is out of the car check this out before installing.
