1972 k20 chevy truck 4×4. 02 crate engine 350 with 290 hp. edelbrock 650 cfm carb and performer intake?

how could i adjust my carburetor. im trying to go for the most performance i can possibly get out of my carburetor. whats the jet size and air/fuel mixture ratio. and how can i tell if my engine is running to lean, i dnt like how its running right now because i down shift and stomp on it and it has hesitation. im looking to get the most throttle response and throttle control i can from this carburetor. how can i tell what my jet size is and if i need to go bigger or smaller. im wanting the most bottom end and tp end i can get so basically best of both worlds. and i was wondering if i could take the choke flap off since i live in california. i dont think i will be needing it. im looking to get answers before i tinker with something im not familar with. im familar with carbs but i dont want to burn my engine up
