Agree with Steve and Fixit. Do NOT drill anything. Try the larger jetting. Would suggest trying 73's first. Always better to go in small increments.

When you do this BEB, go back to the out of the box set-up at the same time. That way you will only have one thing you've changed instead of several. Then if it gets better, but not fixed, try the 74's. I suspect the jet change will take care of it.

As to AF, Fixit is absolutely right. 14.7 is way way too lean for a Holley. 12 to 12.5 is about right. Holley carbs have never been known for mileage and that's why. They just don't work right leaned out too much.
