This head is located in Clover, SC. The casting number is 1241860 and it date-coded 10/28/74. I suspect this is a fairly rare piece. It was on a ‘74 455 I recently purchased that had mis-matched heads on it. I doubt I could ever find another one so I decided to offer it up for sale incase someone out there is hunting one. No springs or retainers. Ex valves are in good shape, intakes are pitted on the back side, some worse than others. Asking $250, buyer pays shipping.
