Rookie building 2056 need help Options

[Lingcuisine]

I am starting to collect parts for a 2056 build. Here is what I am thinking as far as pieces to the puzzle:

Parts I have:
-Purchased a very nice case machined by HAM Inc with main bearings and upgraded case bolts
-2.0 crank
-2.0 rods
-nice flywheel
-fan with A/C pulley (yes I need A/C in south Mississippi)
-Weber 44 idf Spanish made
-have complete 2.0 heat exchanges and exhaust
-complete 1975 2.0 in car currently runs great complete fuel injection leaks oil everywhere!!! Will use what parts I can and sell the rest

What I need info on:
-can I use weber 44 if so who rebuilds them for this size motor?
-will carbs give better preformance than fuel injection? (With A/C)
-If I use weber 44 what cam kit from Jake?
-What heads Jake Raby's RS+ or LE 200 I do want new heads
-Will buy 96 KB pistons and AA cylinders
-stock heat exchangers and exhaust o.k.?

Machine shop:
-What rotating parts need to go?
-does case need to go?
-Piston and Cylinders also?

I know I am forgetting tons of stuff. Please remember I am a rookie and need guidance.
Thanks Jeff
