I've heard the Magnum 360 (5.9) heads are the best small block heads produced, but they have a different angle for the bolts that hold the intake on, so extra work/parts are required to use them on an LA motor. Gene



yes the magnum heads flow great,,but used ones are prone to have cracks in the chamber area,,and use a rocker set up not as good as pre magnums,,,the 1989 heads are same as magnums sorta and use the shaft mounted rocker systems,,
