in my opinion they are a fantastic engine yes they rev and rev and are one of the best n/a engines on the market ,as for torque got to agree with Chip ,they are torquey for an n/a as what your forgeting is the torque is messured over a larger rev range where as a zetec is finished at say 6500rpm most v techs carry on to 9000rpm so the torque reading will took different compared,
Its one of those engines you either love it or hate it ....
