Need a Mopar guru: 273 part-throttle ping driving me crazy!

I have a question (feels like I am derailing [back] my own thread... :D )

Are Holley jets pretty much all the same? I may be more interested (if I have to go into the carb, anyway) to just swap the jets for something a little larger to get a slightly richer/phatter mixture rather than drilling the current jets. I see Holley jets on their website but not sure if they will fit/are universal amongst all their carbs or if the 2280 needs a different kind of jet...

Thanks (back to y'all)!
