Well if it's not the egr or air...my guess is that it's related to the valvetrain. If you screwed up a vacuum line, it would be a whistle or a ticking hiss, I've never heard one "popping."
Depends how loud it is, most LS1s with a cam and even stock motor have a faint tick. If you're sitting in the car with the windows up and the radio on low and can hear it, I would start to get worried. It could be a loose rocker or collapsed lifter. Any SES codes, terrible idle, power loss?
