How to tune ThermoQuad secondaries?

Well, I drilled out the jets with the next bigger size drill bit I have (I believe it's 0.140", I know, probably a bit too big) and it seemed to help a little bit but it still doesn't have any extra pull to it when the secondaries are open (tuning the air door doesn't help either). I'm going to give it a couple more tries on tuning the air door but I think I'm going to end up ditching this carb for a decent used Edelbrock 600.
