[Spridgets] SU Carb Help Sought

[Miniac7 at aol.com]

Listers,
 
I am about to get my recently rebuilt 1275 back from the rebuilder and am  
almost ready to install it in a road car. I would like to ask for suggestions on 
 needles and springs for the twin SU's. Here's the build spec:
 
..Rebuilt and fully balanced 1293 cc
..Lightened rods, and flywheel
..Swiftune SW5 cam
..Fully rebuilt 12G1316 Spridget smog head, ported, 3 angle valve  seats, 
hardened valve seats, lead free, new valves, guides, and dual  springs 
..25 D dizzy using points/condenser
..LCB header to free flow Sportex tuned exhaust
..Twin 1.25 SU with K&N pancake filters, port matched intake  manifold
 
Based on this build spec what needle and spring is  recommended?
 
Once I move to a set of twin 1.5's, what would be the suggested  needles and 
springs for that application?
 
Thanks for any help you can offer.
