Idler arm hits on header
Even the most expensive headers won't fit every car. Mopar was sloppy when they welded up the k-frames. My car always was a nightmare with headers. So much I went back to manifolds. But when I dropped the stroker in I went with TTI headers. They would not fit. And the reason was because my k-frame was sloppy and the engine was not sitting in the correct location. I had to notch the motor mount slots to push the engine back and place shims between the motor mounts and k-frame. Pushing the engine back gained tons of room between headers and steering linkage. Shimming took care of the torsion bar interference. Used a Shumacher torque strap to keep engine from moving under load. Took about a week to get it all figured out. But after that the headers bolted in and cleared everything and no dents were required. Had to bend up new trans cooler lines but thats another story.
