So if I understand the concept correctly, leaving the stock intake and 1 barrel carb, stock cam but maybe do long tube headers and a 1 into 1 exhaust would give as much low end torque as possible with this engine without using a supercharger.

What about bumping up the compression ratio? Will that help? I have higher compression 292 pistons (approx. 9:1 ratio LPG pistons).
