Possible to use the jets and rods off SB and set up like SB?
For sure. Swap primary jets and rods complete with rod plunger and spring, secondary rods and hanger, accelerator pump and you should be good to go.
Also, when the engine is idling, check that there is a small amount of clearance between the choke pull-off rod and secondary air valve arm.
When the secondary throttle plates are opened, the air valves need to immediately snap open a small amount to expose the secondary pullover bleed holes to manifold vacuum.
