Six Pack Carbs for Manual trans any difference?

I heard the new repro carbs have a lot of the tuning issues taken care of. I sure jetting them if I have to is no problem.

Ha I wish I could go efi but that requires new $800 tank and the cheapest I have seen for efi is $1850 for the EZ. I got a good deal on the six pack intake so I am trying to piece this together without the wife finding out. Ha!
