Twin Valve Springs
#6
Need only be sufficently strong to place bounce revs somewhat above used revs. On standard geared standard non sports models over 40 mph in 3rd (or 2nd)....... Stroger springs just add friction and wear.
For decades I ran a Jowett Javelin. These wear non replaceable cam bearings which with a flat enine is significant. Also wear valve seats, partly due the cam wear. I eventuaully ran mine with inner spring removed. Valve bounce was 65 mph but it was driven great distances at 60. Seat wear reduced.
