If you don't plan on racing in a class that requires a stock type front suspension.........I would dump it all and go struts. Struts and a rack are relatively inexpensive, plus an easy install.

Stock Mopar front end stuff is a pain. Box is in the way, drag link in the way, heavy, etc. And while the headers you show seem to clear everything...........they look small, likely have tire clearance issues and the plugs look like a nightmare.

Race cars should be easy to work on. That and light weight are two of my most important things to consider.
