602 crate- carb question

[Dirt racer 10]

I'm interested in opinions on the best carb for the 602 crate. Is it worth spending $1000 on a carb? What has everyone had the best luck with? Wily's? Aed? Regular Holley hp?
I currently run a Stock Holley with vacuum secondaries. It appears to me that the secondaries rarely open causing a lean condition during race conditions. I am very new to this so tech support and having the carb pretty close out of the box is important. Thoughts?

if you dont know much about carbs then its def worth $1000. when i first started racing i new nothing about tuning a carb i bought a blake carb for my limited it was 1000 i didn have to touch it for 2 years. ran great right out of the box. when your in the pits and the guy next to you is scramblin to fix his carb and yours fires right up you will be glad you spent that money.plus if you go w a brand name like willys stealth brasswel blake gaerte they all cost about the same and later can still sale it for around 4-500$. alot of power to be found in a carb also. i would say its a must.
