Mopar Head?

Has anyone have knowledge about and or used this head casting 2402557. I'm not seeing this casting number in Senatore listing. Is it maybe a replacement head for a 361/383/413?

Thanks for your help.

Ok, I found the casting number on the Allpar site and it comes up as a 413-300J head casting number. Can anyone out there have some insight about these heads. I've only seen pictures and they are reported to make a 383 run like a raped ape. Thanks FABO
