I have no idea how the OP's heads are prepped, or what they flow.......so I can't really speak to what I would or wouldn't do with his particular heads.

What I can say is that "generally" the 572-13's are a bit weak on intake flow(compared to something like a B1) til they get to about .450-.500 lift.
The ex side of the head is usually pretty good.

So, "I" would probably run a more aggressive intake lobe than what I think his cam uses, run less split, and a tighter lsa.

But, both the previous cam and current cam have been speced by builders who have more experience with that type of build than I do.

I feel like it's pretty hard to really evaluate two different cams without a trip to the dyno.
Sure, ultimately it's how the car runs that really matters...... But there are also way more potential things in the car that aren't working as they should, that could hold back the performance and not allow a better piece to shine.

As I said previously....... I doubt whatever I might have come up with would be much different in terms of power.
It's not like the current cam is out to lunch...... Any change would be more like a tweak.

If you look at the cam tests Andy has done with the 470's, you can see its pretty difficult to make a big change in power by changing the cam, if the current one is close.

Here's how the cnc 385 572-13's I had here compared to a couple other heads through .600 lift.
All tested on a 4.500 bore:
Intake port only-

A- cnc 385 2.350 valve
B- cnc 345 2.250 valve
C- original b1, mild port, 2.300 valve

Lift------A----B----C
.100---58.9/ 74.8/ 73.7
.200--121.2/157.6/148:8
.300--188.4/218.4/219.6
.400--253.1/277.5/284.2
.500--312.2/329.8/338.4
.600--370.0/360.5/375.6
