Consider yourself lucky. I have a mild cam...only the E-303....and I get random surging, except mine, if left to do it, will go from mild to severe surging and then choke and stall. I hear it's a problem with the IAB valve design being too restrictive. I think you can order a part from Ford that fits in between the IAB valve and has a screw on it that you can turn to let in extra air. I guess it works, but I've yet to try it.
But try cleaning the valve anyways, just to see what happens. Oh and I noticed you call it an "IAC" valve, instead of "IAB".....didnt use to own a GM by any chance did ya?
