Retune my entire carb after installing new heads?

No the over emphasis on that one aspect

And you wonder why some engines make more torque than others........So put a bigger carb on and then complain it doesn't make any torque down low so now you need a big stall to get it to launch........

a lot of time it's easier

Its easier to put a smaller carb on to fix a problem than spend hours posting on forums searching for a solution to a problem you created. How much time has this guy spent changing TSR's to get the transfer working right.......The whole point of running a smaller carb is a smaller throttle bore increases vacuum to aid the idle and transfer circuit to do its job effectively and properly ie condition the cylinder to take on WOT mixture correctly. Remember my statement from a previous thread:

Engines with lack bottom end power?

Less firing events equates to less force transferred to the crank does it not? So the quality of those firing events becomes critical in the torque generated does it not?

Its the efficiency of each firing event all the way through the entire rev range that accelerates the car not just the top end. The most critical is the low speed running circuits BECAUSE they set the stage for HOW the cylinder fires. So Mark Campbell fixes the low speed running on a Prostock car and the car goes FASTER. Did the car now ingest more air to make more power or did just do it more efficiently? If you're loading up plugs and creating a less than ideal cylinder condition then when you introduce the mains fuel its gonna take a long time to get back up to peak efficiency before it can make peak power.
