Centerlink angle , BB Kframe

Not normal on the stock K. It will cause steering problems.
Is the K bolted up to straight frame rails? Is the steering box properly installed? And the centerlink hung on the studs? And the arms are straight back, parallel to the vehicle centerline? And the chassis is level,from side-to-side? If all are yeses, the steering box will have to be shimmed. And/or the idler arm mount,slotted. It's best to have the engine/tranny installed first, and the headers on. You will want to do this on the alignment rack, with the car at ride height, and rake. Some of these changes will mess with your camber curves and bump-steer.Your alignment guy will need to fix these issues.
