On some headers you have to remove material from the frame. Grind it or cut it out.

Sounds like you may have to dimple that header tube, or do as described above.

Hitting the cross brace? My Hookers hit there. I had to cut off the raised corner part of the brace to clear. Without this, I could not get the header bolt holes to align.
