drilling or adjusting the set screw is only necessary if your IAC is near or at its operating limits. During hot idle, the IAC counts should be in the 60-120 range.
But what your describing sounds as if your throttle follower is decaying to quickly, desired idle speed too low, or that your base spark drops off too quickly
