VTEC head for B20A?

I've heard of people going "CRVTEC" with the newer B20-block swaps, and I'm wondering if the same thing or something similar could be done to the JDM B20A. What kind of performance gain can you expect and what's an approximate neighborhood of the cost for the headwork? Could the stock head be used or would you need a head from a VTEC B-series engine like they do with the CRV conversion?

From what i understand it wont fit like the CRV b20 but it can be done. Tom at Ludespeed has done it to the prelude B20 but requires a bit of fabricating it to fit. And I done think the CRV parts are transferable.
