Not sure if there is a rich enough standard needle though so that might also need modifying, currently running one of the richest needles and that is just with a stub stack and K&N filter fitted which gave a good increase in flow.

On an A-series with a relatively short inlet manifold that would help, not so sure you'd even notice the difference on something twice the size in terms of capacity and with a relatively larger inlet manifold.
What oil are you using in the damper?
Also if you want to really increase power/flow capability, have you considered an SU HS8?
Gut feeling says you'll lose driveability by modding your Stromberg that way but i've not tried it so can't be certain.
