The Bulls - who not long ago were 33/1 - are now 5/1 to win the division, alongside Macclesfield.
Hereford are currently three points clear at the top with 22 points out of a possible 27.
However, despite Saturday's hammering, South Shields are still the bookies' favourites at 4/1.
Meanwhile, Morecambe and Oxford City are both priced at 11/1, followed by Chester at 12s.
