I have to disagree about the Magnum rocker system being Chevy style. It is not. Chevys use a stud which can flex terribly. They ARE certainly inferior. The Magnum engines at least incorporate a bolt down tight bolt mounted rocker system. While they are not as good as the old shaft mounted LA style, they are FAR superior to the Chevy stud mounted rockers. Their only drawbacks are they are not adjustable and they will not stand a lot of lift. But they will out perform a Chevy stud mounted rocker any day.

The simplicity of the Ford/Jeep / Magnum setup,has it's merits. I went to stud conversation on my Magnum,without considering the 1.5 LA rocker ratio, to the 1.6 Magnum setup. I slid in the LA hyd roller ca!m, pegged the 1110 Hughes setup. Sooooo , I went with the Crane stud conversion setup. It was nice to actually be able to adjust preload personally. So the tradeoff is adjustability vs. optimum valvetrain stability. At valve spring psi 110 on the seat, 300-310 on the nose, not too worried about it with a hyd roller...
