do you have any 1/4 mile passes with that setup?
one thing to heavily consider is that peak dyno numbers don't tell the entire story on performance.
i don't think a ported stock cast cyl head and LT2 manifold is going to get you anywhere near 600 on a legitimate dyno.
how much are those heads milled? what gasket are you planning on using? stock valve? quench?
edit: do you care to share the cam specs?
