My tip from restoring Tripower carbs is to use the original style and size inlet valves.
Any other style have issues with flooding and/or restricted flow.
Also check the size on seats for 1966 factory sizes .120" in center carb and .086" in the end carbs.
1965 center uses a .100" inlet valve end carbs .086" as all other 1959-66 end carbs.
