Are you talking about a stud girdle for your valvetrain, or a main cap girdle?

I would prefer to use an individual shaft rocker sytem to a rocker stud girdle.

I would go for a 4 bolt splayed main cap conversion before I'd use a main cap stud girdle. Some engine builders believe that main cap girdles can contribute to transferred harmonic vibrations / loads that wouldn't otherwise present a problem.
