These stud girdles will not work with center bolt valve covers and the valve cover bolt would have to pass through the girdle. Machine work on the girdle would possibly solve the problem but would take away from the integrity of the girdle. The other option would be to use an earlier valve cover adapter in conjunction with the stud girdle.
