As other's have mentioned, the piston valve reliefs are different for 572-13 heads. 13 degree vs 15 degree, moved location.

For the real step-up, the B1 originals would be my choice. But if you have fairly new 440-1 heads, and you said no porting, there may be room for much improved porting to around 375 cfm with the 2.25" intake valve. I don't know if your current port shape would interfere with the current CNC porting programs for 440-1 heads. OOTB 440-1 don't flow well at all, so a CNC would be a big improvement, IMO.

You will need to check your piston valve reliefs if you change to the 440-1 2.25" intake valve. Some are OK, some are not.
