Will,
You should not have to drill the MB, as you will find that the idle is very sensitive to the amount of gap on the throttle blade. You can adjust the IAC and just leave the throttle blade slightly cracked to get to your idle quality. I found when the "flap" is closed that the IAC has great difficulty in controlling the idle level steady. I have a minimum opening set in FAST, and the "flap" open a bit. This may be due to my cam as well.

Best of luck with getting it installed and tuned properly. I am happy with mine now, it just took a bit of work.
