without building up the head i wouldnt recommend it. maybe like 7300-7400 tops. plus the head is stock with stock cams, so it wont hold good power that high anyway. id say 7200rpm sounds good to me for now

ls motors (b18a1) redline out a 7200, with the ls rod ratio i would not go past this with stock internals, like stock ls rods. now if you had forged internals with a better rod ratio, and some head work to go with the internal work then reving past 7200 can be done safely.
Can you spot me 20 cars?
