Hooker had a header that made contact with the steering shaft, I dont recall the # of that particular header, but try a speed shop or Joe and AJ here are very knowlegable and helpful on what will work. There not much in economy headers for magnum swaps into our cars. Tri Ys are a good bet. You might need to move the collector up to avoid scraping the ground, or you may just have to raise the front up an inch. Its a tough deal with a truck only engine and Mopar being so small before they came our with the Hemi and a transmission that would last the life of a truck. Theres compromises that will have to be made. Taller tires will help and fill the wheel well nicely, a few turns on the torsion bars, maybe pounding a dent into a header tube are common answers to common problems. Without buying more expensive parts, your going to have to do some modifications and maybe settle. Theres always a way around most obsticals. Sometimes a bigger hammer, sometimes a cutting torch, sometimes its having a shop get involved. But guys put magnums in cars every month so nothing is impossible, it just might need modification. You have a 5.9? If so you will need a 360 center sump oil pan. Not a 318 pan, unless its a 5.2. Thay are different.
