The limitation is the maxiumum port volumetric flow rate compared between the vtec heads and the non-vtec. worked non vtec heads will not flow as well as worked vtec heads ever. Fact. You can run all the boost in the world but if you aren't flowing it through the head it will be inefficient. The ls rocker arms are also alot more unstable at high rpms than a shaft mounted rocker in a vtec head. Try running a non vtec head to 10 grand a couple times and see what happens.
