Can someone help me understand how the replacement head for the Mopar 440s is rated less than the factory head?

440/375 rated at 350 with factory head, 345 with replacement head
440/390 rated at 395 with factory head, 391 with replacement head

What am I missing here?

Easy, the new head has not gone as fast as the old head. I think it's called the letter of the law.
