Are these Hooker 5303 A body headers?

[4mulas]

Looking to see if anyone can confirm that these are 5303 hooker’s? @Newbomb Turk dont you love these things? Do you know if they are the 5303?

I have a chance to buy some and just don’t want to end up with a wall hanger.

Numbers should be stamped on the head flange

They look like 5303's
