Curious what's out there for a header for my 440 dart sport

Well good! I am glad you got them to work. I'm sure these guys would love some shots of the dents so that might help them as well.......if you can get some.
So after all this time I stand corrected and the other gent was right. I wasted a lot of time putting them in and marking them then remove them and massage them with a soft faced mallet. The engine never sat right passenger side header was on fender well just wasn't working out. Finally broke down and ordered TTI RB 440 headers. Been fighting the wrong part for so long and getting really good at R&R ing these pita headers that when I had the right part and was installing them they fit so good almost fell out the bottom haha wasn't expecting it to go this easy. So if I can save some hard headed guy grief and lost time listen to these guys they have a lot of experience between all of them. They look good and sound great happy I bought the TTI headers just wish they were priced for the working man.
