No I haven't had any problems, they are just a copy of the sbc pushrods. This setup that the magnums have is very similar to the oldsmobile engine from the past. Comp cams has been building this type of setup for years for them.(olds) In fact I believe that comp cams is making this setup for the magnums now, if not mopar has them. They kind of remind me of the ford 302-351 steup that crane cams offered in kit form. Mopar sells it in kit form also,with roller rockers.
