On the right side? I think I know what you mean. I got a macs header pipe laying around someone gave me. It has a macs sticker on it I think for a 46-48 ford. Were the pipe turns and meets the manifold flange it runs full size into the flange. The original necked down. Im sure its done for manufacturing expense.
