You're probably experiencing the differences between the choke pull-offs, since they also affect AV opening.

Just adjust it the way it's supposed to be, and don't worry about it.

Your rods and hanger may be on the lean side as well.

My car felt similar to what you are describing. My problem turned out to be the timing. The lighter springs in my distributor were allowing the weights to swing out while at idle. So when I set my base timing it was already advanced and no additional advance was available at higher rpm. This made it feel dead above ~3500 rpm. Just mentioning this to give you another possibility to rule out. Make sure your total timing is reaching ~32-36 degrees by 2800 rpm. Makes all the difference!

My car liked the DR rods, even when stock, vs. the CH's.
