I think we have discussed your balancer hub earlier?
The conclusion was that your hub is a factory 1964-65 vintage for 1964-65 timing cover with just a pointer thus the two marks, first mark indicates 6° BTDC and the second mark 0°, instead of one mark on hub (0°? for the scale on 1966-67 vintage timing covers.
Your engine builder simply mounted the wrong hub for your damper.
And, the need for setting the timing out of the scale indicates a too lean F/A mixture. The carb needs to be recalibrated for todays fuel to let the engine give its full potential. This will not happen igniting a too lean mixture with timing set out of the scale.
Also, a too lean F/A mixture will make your engine run hotter than necessary.
