I think they all flow about the same AFR, Dart, Brodix depending on runner and valve size, I think it boils down to preference and budget
Edit: buy them bare and have an experienced builder put them together to match the cam and other valve train components, jmo
Edit: there's a few threads about this

Looks like the 4 heads, with CNC porting, were all close to each other power wise. The AFR and edelbrock did have one advantage, with their smaller chambers, probably bumping the compression .75 higher than the dart 335 head, that only made 12HP less, and 20ftlbs less than the afr.
That E-CNC 355 head, looks like it did pretty well. Probably would be a killer head on a 572ci setup. For 1000 bucks a piece bare, fully CNC ported, that seems like a good casting to assemble.

Take a look at Brodix's newer BB-3 Xtra O 332cc CNC head:

That's got a marine 540+cid all over it !
