I actually feel that they’re easier to dial in for street duty when the cam is on the big side(lower engine vacuum), since that’s what the low speed circuits are designed to be used with.
I like to use one of the original non HP list # 9375 for a single plane intake on the street and at the track I due lean down the transition circuit to keep the motor happy(spark plugs clean) and not real fat at part throttle cruise
