edelbrock heads

does anyone know what makes the performer RPM heads non-emissions and performer heads emissions? and do the RPMs put out more power over the performers??

The emmissions legal heads have provisions to hook up the thermactor system to the back of the heads. Non emissions do not have these. Pretty sure the rpm heads flow better than the performer heads though.
