While we're this deep into the discussion of valve springs, I'd like to find out something I've wondered about for a while. According to my 1956 Motor's Repair Manual, the valve springs on all 1955 engines had 66 lbs tension and the 1956 all had 92 lbs tension. Is this correct? If so, one of my theories as to more "lifter noise/problems" on 1956 engines *could* be caused by the increased pressure, no?
