No question, AFR makes some really nice 23 degree heads that perform really well. Specifically, their 235 and 245 Eliminator series, but they'll also cost you a few more bucks over the Pro-1s.
Recently, I've been buying my Dart heads bare, then selecting my own preference valve train components. Like PAC springs and retainers, and Manley Severe Duty + .100" valves. Then have them locally ported!
FYI, CNC-Motorsports built my Dart block SBC 427 short-block assembly and they did an "outstanding job" with the engine build. It has run some 9.0s @ 150 MPH in my tube-chassis car!
