These headers where in a low 10 second '65 GTO with a 468. These are race headers and have no flange to bolt mufflers. The pan evacuation tubes are installed and collector wrapped to keep heat from transmission. There are a couple of small dents and the necessary dent for steering shaft. Nothing on the bottom since car always came down easy. These where $500.00 new. Will trade for 1 7/8" Small Block Chevy headers that fit a '68-'72 Nova or $150.00.
