Has there ever been a BBF cylinder head comparison?im searching all over the net and cant find ANY articles where they test the Trick Flow Streets. I dont want just head flow data but an actual buildup would be interesting. They should do a comparison on a 460 (or stroker) vs. edelbrock heads and other heads in its class.Has anybody HERE done a comparison? that is, using the same cam and intake and things like that. Im talking about out of the box not ported,because unless its CNC, no two port jobs are really the same so the integrity of the test would be sacrificed.
