Seems like the 461 head is only legal up to about 1966 cars, the 462 head is legal from '61 to 68, the 041 head is legal from '61 to '70, since most new stocker projects are newer than that, the 041 head from '69-70 would be a better head to get, since it has a far broader range of applications.

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?

It's like the 993 casting for the '70's cars. Legal replacement for a lot of cars, for sure.
