Not always. A port with good low lift can carry it through the lift curve but I've never agreed with DV and his thoughts on low lift flow. I really could care less about low lift flow. If the port is correct low lift really means little except at overlap and that's when big low lift flow numbers kill power. And then to fix it, guys want cams with early closing intakes and wide LSA's and it's just a bandaid for a poorly thought out port and valve job.
