How to make a 1050 Dom list 8896 streetable

[68 C-10 KID]

Short story is timing belt broke. Fixed it all up. Decided to changed the intake and carb combo from a pro dominator with dual 750 Holley to a super victor 4500 flange with a 1050 dominator. (The KID in me)
Rite out of the gate the idle circuit is rich and the low speed cruising around town is fat, lazy, and blubbery.
The 1050 is a 3 circuit. I should be able to tune all of that out. The question I have is we're do I start 1st?
The idle curcuit in the metering blocks (jet size)? Followed up with the low speed air bleeds (jet size up to slow things down)? Should I get into the intermediate air bleed for the rich conditions while cruising?
Thanks for any info that will help. I'm trying get this combo tuned up for a 4 day bracket race event in Eagle Idaho called the Halloween classic.
