Headers small block wanted

Hello Kentucky, Just for reference I used a set of Doug's headers on my 72 Duster 360/410 creation Small block set up. The big downfall is you cannot use transmission to engine braces. Both have to be installed from under neath as i am not running a stock front end (Control Freaks) with a rack n pinion steering system. The drivers side was tight as it was really close to the steering column.
Personally I think all headers are .....Just a chance even though they say they will fit. The Doug's headers are a the 1.625" inside diameter. Hope this helps... Texas Red
