The best way (i think) if you still want to drill you should use a carbide mill (flat bottom) instead. And a carbide reamer to finish it.

Wow, old motor finally let go. That was some serious power...... made me feel like I was driving a yugo when your FD pulled away from mine! Hope the new build goes well. Hope Family is doing good. Holla

Het Chad! All good down here. Yeah motor cracked a front plate at 700hp. So if this next motor last half as long I will be thrilled. Last motor was low quality but was bullet proof. Now I am trying to build this one with quality parts. My luck it will break on the dyno!

I don't want to say you're screwed but... It is almost impossible to "center" the drill bit on an existing hole using a standard drill press and expect accuracy. How did you determine the center? Because those drill presses have excessive amounts of deflection in them, you may be off one way on one hole and off the opposite way on another hole. That equates to the binding. You need to have them cnc'd or center bored and tapped on a "manual" milling machine. I worry about the longevity of your engine if they are binding at all.
