There's no way Naruto will reach 4 tails for a fight which I assume is friendly.
He should be able to defeat Lee with clone spam, he's not enough of an idiot to attack the taijutsu expert in close-combat after all.
If you restrict 4 tails then Lee stomps. If he goes 6 gates his speed and raw power are too much for Naruto. He can dodge all FRS and stomp all of naruto's clone in an instant. (ofc i'm refering to the Naruto that fought kakuzu).
With 4 tails allowed Naruto wins
Oh it ain't friendly, Naruto done smacked Sakura for the last time.
