First-half goals from Tom Pope, Jennison Myrie-Williams and Louis Dodds sent Vale to the top of the League Two table after an away win over Dagenham.
Micky Adams made one change to the side that defeated Rotherham with Calvin Andrew replacing the injured Doug Loft.
And Vale got off to a dream start when goals from the prolific Tom Pope and Jennison Myrie-Williams made it 2-0 after nine minutes. Dagenham pulled one back on 16 minutes, but the points already looked secure on 39 minutes when a lob from the in-form Louis Dodds made it 3-1 to the visitors at the interval.
But Vale had to survive a tense closing period after Dagenham pulled a goal back with four minutes to go.
But Adams’ side held on for a win that takes them to the top of the League Two table.
