Magnum heads on an LA enigine

According to comp cams desktop dyno my magnum headed LA 318 is making 320-330 hp and 350-360 lb tq. That is with a smallish 256 cam, but my bottom end is flat top pistons and it put my compression ratio about 9 to 1 using .026" head gaskets. Magnums also come stock with stamped 1.6 rockers so you can take advantage of a little more lift. Runs good for a 318.
