Casting #'s?
.......I'm picking up a spare set of heads to build up for my 305....I just need to know where to look for the 416 casting # I on the head itself....where on the head will it be? Or is there some other # I should look for to verify the heads are the 416's? Thanks.

Underneath the valve cover...416 will be the last 3 digits of the casting number.
Edit:
On the head itself, not on the valve cover
