The box mine came in said they fit 64-72. I have them on my 75 Lemans, which can use 2nd gen F body headers. Yes they are obviously round port, and I had to slightly open up a couple holes and ding one tube, but do a search and you will see there's no perfect set of on the shelf, ready to ship, thick flanged, stainless headers available at anywhere near this price point.
