AFR heads: Good Choice?

k.. bored at work and wanted to look up this stuffs...

Earlie A here on the forum did some tests of SM/Edelbrock heads and they flowed around 270 unmodded (the SM flowed a few cfm more)

this is from AFRs page.. And that is just sad.. they are as-cast ports no cnc porting.. for a street car/driver you probably wouldn't notice.. but just the lack of inspiration from AFR is annoying me..
