Bolt On 50 HP With Ford’s New SCJ Heads
Ford’s Super Cobra Jet head is sold bare or with valves, springs, retainers, guideplates for 5/16-inch pushrods, or rocker-arm studs. Other 429/460 guideplates won’t work due to the new head’s revised valve angles. Ford sells the new guideplates separately in kit PN M-6566-SCJ. View Related Article
