Cool Re: SBC 461 heads

Alright, I have a 3782461 head that someone told me was a 461X casting. I don't see an X on it anywhere near the casting numbers, I remembered seeing 461X heads that had the X at the end of the casting number. This head has a date code of G 111, but it does have a small X on the bottom of the head right below the water passage near the deck surface and between the intake gasket surface at the water crossover passage. It has 1.940 intakes, 1.500 exhausts, and looks like an original old head that might never have been apart. Where was the X that designated this as a 461X casting?
