Disregard if using 442-5727 Valve Cover Base.The preferred method to correct this issue is to remove the former 222-6953 Valve Cover Base and install the current 442-5727 Valve Cover Base. This valve cover base removes the need for the 444-2472 Bracket As and 444-2473 Bracket As.The alternative method is to modify the 444-2472 Bracket As or 444-2473 Bracket As to be used with the 222-6953 Valve Mechanism Cover Base and stamped steel valve cover.Note:
