596 heads on -68 340

They are not 100% faulty of course. But then the unhappy people on the forums with cracked heads, different spring pad measurements etc arent happy with theirs. Im sure someone in the 70s bought and used a Chevette and liked it. Doesnt mean for the price they paid, it was a quality piece. As a fellow fabo member I hope you dont have any problems. Its not like just having to yank a bad carb.
