Yup, stock exaust go with more, if you get something thats not as restrictive you can go with less.

This is how GM designs their cams so i would have to agree with this thinking for near stock application.

I agree with everyone u cant have to much air coming in if u cant let it out. 02 Z06 cam would do alright with stock manifolds.
