Poorly defined question! What is "normal" flap setting? It will vary with weight, runway length, thrust setting, a/c type etc...
A "high" flap setting will give an earlier lift-off (TOM vs. RWY), but that extra flaps, regardless of how much, will always give a drag penalty (no, that extra lift will never compensate for it), thus resulting in less performance and you'd perhaps have a hard time reaching the 35ft screen (since take-off distance is measured from brake release to 35ft for JAR25 a/c).
However; it also depends on whether or not you alter your Vee-speeds. Next to impossible to answer that question without further information :-)
