The listing spans catalog appearances from 1971 to 1972, but we don't have anything more specific in our records tying it to a particular model or engine size. Given the complete-assembly nature of this part, it's worth confirming fitment carefully against your engine before ordering — a cylinder head is not a part you want to guess on.
