Feets,
I went to the garage, cleared stuff off a 440 (with E heads) and measured from the valley pan (rear side) to the top of the carb pad on a Performer RPM. 6 3/8 inches using this square.

You should do the same on yours. Subtract yours from my 6 3/8 to get your expected height increase.

Make some pencil-diameter spikes of modeling clay about 2 inches long. Stick them on your current aircleaner front/rear/left/right. Close the hood gently, open the hood gently, measure the spikes to see your current clearance. Obviously hope for a number greater than the height difference.

Funny how I can do this, and yet not keep my car on the road.
