The gasket flange on the chrome valve covers will distort and the aluminum valve covers will crack or break around the bolt hole covers if overtighened. I think it is just personal preference what type of valve cover you use. The brand of valve cover and the gasket will be the determining factor on how much they leak or don't. I have found out myself that cheap valve covers and gaskets just don't seal.
