I think saying 930 heads suck big time is nonsense, they may require more machine work than a carrera head to mate up with the carrera intake manifold, or they may need considerable porting to match your performance goals etc etc, but it is FACT that the carrera head is made from an inferior alloy. Carrera heads may well be ok for a street car that sees very little WOT, but for a properly built engine put through its paces on the track they simply wouldn't last.
