They are rare and pricey, can't remember casting numbers off my head. Seams like I saw pictures in the Big Block section, and I am too lazy to get mine down from the attic. It may be cheaper to buy headers, although I do not like them. The stockers run good, I've had an original 68 Formula S for decades. Even used it as a daily driver for years. It was automatic and would go sideways about 2 feet from first to second. If you want a pair, post a want add?
