how fast can i spin my balanced shortblock??

I have a fully balanced motor consisting of stock crank turned(.10), rods, and new forged pistons. the rods have arp hardware, and I am going to add a girdle this winter. I have roller rockers, aftermarket cam, ported p heads, ported intake etc. The car pulls hard past 6k, and I have the tweecer hardware so I can disable my rev limit. also, I am running nitrous on it. I have been hitting it with a 100shot, but I am going to step it up to 200. Right now my window switch is putting it on for 3000 to 6000 rpm. Can I shoot higher??
I have a buddy that spun his completely stock 5.0 to 7000rpm, but the stock rockers flew apart. What am i capable of with my combo???
Thanks.
Ted
