1972 318 need more power

Typo on the v6 of course
Have headers and duals. Does seem like timming a little off. Have electrnic points rest standard. Lots of moisture out exhaust when setting long periods of time but no leaks. Temp is fine so maybe retarded a little. Have small elde four bbl and matching intake. Slight indication of too much gas on kickdown but smoths back out in a second or so. Thinking heads with bigger valves and try to up compression on cc size???
