what vacuum are you getting at idle in gear , the springs need too be lighter rated than the reading you get so if you have say 6" of vacuum you need 4" springs

I need to go find out.

im wondering why the front carb idle mix crew is sealed.  Is that the way they should come?  Up front, in my mind, you should be able to adjust the idle mixture.  I though sealed mix screws were an emissions thing 

Last: Are these carbs new or rebuilt?

All factory Hemi carbs: the front carb are sealed off idle screws.
Scott Harms rebuilt these.
