Are you remembering right? I don't remember bringing you a set to modify. I did send Mark a set of Clifford 170 headers, and a set of 225 headers. He did modify them so his would work on both the 170, and 225 engine in a 66 and down "A" body. I haven't tried them on a 225, but am running them on a 66 Valiant with a 170. They are close to the torsion bar, but don't hit.
