u'll find it very hard to get to redline sam.
if your stuck on the low cam profile your motor will run out of puff way before redline & will just have nothing left to push u there.
the motor will start getting upset as the airflow starts getting choked up thru too small of a valve opening,not good for a new motor.
just stay in the working range of the low cam till u get vtec hooked up,your motor installer is quite capable of getting vtec hooked up for u,if u want it done straight away.

have u sorted out the dizzy yet?
