Sbc for my cj5 build choices

I have a '76 SBC 350 .030 over with flat-top 4 valve relief federal pistons that I am rebuilding/refreshing for my ’76 CJ-5. The heads off this engine are 388's with 172/150 valves and 74cc combustion chambers.

I have a few head options and need some advice. I am looking for good low end torque and respectful horsepower. My driveline plans include the SBC 350 engine, SM-420 or 465 transmission, Dana 20 or 300 transfer-case and the stock axels with 3.54 gears.

What set of heads would you guys use for good low end torque?

388 smog heads with 172/150 valves and 74cc combustion chambers
These are in my garage and only need new valve seals.

920 smog heads with 194/150 valves and 74cc combustion chambers
These have been rebuilt and are for sale for $100.

SBC 305 heads with 185/150 valves and 60cc combustion chambers
These are in my garage but will need a complete rebuild.

Let me know what you guys think…

"Americans love a winner. Americans will not tolerate a loser. Americans despise cowards. Americans play to win all of the time. I wouldn't give a hoot in hell for a man who lost and laughed. That's why Americans have never lost nor will ever lose a war; for the very idea of losing is hateful to an American." Patton's speech to the 3rd Army on the night before D-Day.

personally id toss the 305 heads onto it just because it will increase compression and give you more torque.
