Help I.D ing these aluminum heads please?

They should have a p5153524 part number engraved on the end of the head if it is a Mopar performance "452" head
 
As picky as Chrysler is with copyrights, I'd think they'd have one hell of a time using Chrysler part numbers. That is a Chrysler casting number digit for digit.
Chinese don't care about copyrights lol
