Brought Dart to shop to fix idling issue and car runs like s**t!

Yup Rusty same shop that did my clutch work. I know this place hasn’t started on a high note. I believe they rechecked my rocker adjustments which could be hard to do if several of the lifters are shot. The ede heads were gone through by a mopar machine shop I have used and trusted they checked all the tolerances out of the box and recut some of the valve seats before I bolted them on. Idle vacuum right now is at 10inhg. I checked it today when I drove the car. I think with better tuning I could get it up to 12-14inhg. Yes I had the car out driving around for about 30 minutes it had fully warmed up. Thanks for the suggestion mbaird I’ll check out AJ’s tuning tips. Could the lifter issues be the cause of many of the problems?
