When you say production head, which one are you refering to. The N351 was never a production head but it is legal for SS/CS. As far as legal aluminum heads for other classes I have seen some pretty impressive flow numbers for the Z304 head. The number I saw on one porters website claimed well over 300 cfm for a ported Z304.
