I'm selling a pair of Camel Hump heads that were off of a 327 from a 67 Camaro. Casting number is 3890462 and they are 64cc. They have screw-in rocker arm studs and pushrod guide plates. I'll include the valves and valve springs with them too. Would need new valve seals to run. If you want to see some pictures I could e-mail them to you. Asking $200.
