Do your headers have Hooker with the Heart stamped 360° around the Collectors ?
The earlier ones seemed to have this along with a application/ part # stamped on the head flange.
Later, in the 80's they went to the tack welded on plate to the drivers side primary tube.

Those aren't mine but are a recent CL listing so I don't know if they have the heart stamp.
