For ME, knowledge is power. My first Mopar header install was the 5903 pipes in my 440 Charger. I didn't know about the various obstacles with these cars. I was used to Chevrolet cars. Front steering gear and coil springs leave ALL SORTS of room to work.
The TTI headers come with INSTRUCTIONS! Hey other guys, ARE YOU READING this???
When you begin the header install, it helps to go into it KNOWING that it isn't an easy job. My problem is that I am an optimist and get annoyed easily... strange personality mix to live with being a Mopar guy.
REMOVE the center link. REMOVE the starter. If you have access to an engine hoist, use it instead of a floor jack under the oil pan. When you do this job with open eyes, it isn't that bad.
