If you have the original WW carb it should be jetted already for boost enrichment. So double check that first. Then source some bigger jet numbers and rejet based on A/F readings under a chassis dyno load. As for the 2 barrel tall intake have the plenum and port entrance runners ported and opened up some. The exhaust crossover cavity surrounds the upper plenum so keep that in mind.
A good 30 + years ago I raced a Hawk with the GH 57 Blower carb combo. Moved it gradually into the low 13's and a best of 12.98 with the VS blower and 2 barrel. Heads were set up just like yours (early DD mods) and R cam, 3.54 posi. The blower though was modified for fix ratio by removing the variable ratio inner spring and locking the slider pulley to a near minimum diameter. Fuel pump was carter boost reference R2 design. That's my limited experience with blown 2 barrel WW induction.
Good luck and hope this helps.
