I've read not to take a built (forged internals) LS/VTEC past 7800rpm.
91civicDXdude is right about that stroke. The Rod to stroke ratio is not good. Its like 1.54:1. Perfect is considered 1.75:1. A B16 has a R/S ratio of 1.74:1. My Mitsu 4G63 R/S ratio is 1.70:1 I believe. A GSR B18C1 is 1.68:1 I think. The lower you go from 1.75 the more likely you are to throw a rod. Just dyno it with your current setup and see where the max HP is, if its a street car it will probably be 7000rpm at the most.
