Concobra,
950 is not too bad considering a Holley HP is very close to the same price and they don't work all that well out of the box.
As for milling off the air horn.
You have to mill off the air horn or you will get no air into the carb. The hood on most of our cars is quite low, which is quite problematic with the air filter. The original style air cleaner is so short the top of the air horn is right up against the top of the air cleaner...with no room for the air to get in. (Seat of the pants hp mind you--after milling of the horn felt like we gained 100 hp...no kidding.)
