building a hood

i am in the process of getting a 6 inch body drop on my s10 and everyone is telling me that the hood that i have now wich is a cowl hood i think 2 3/4. will not work with a 6" BD. Does anyone know if you can use a cowl hood or you half to build one or fabricate one. Or will i half to cut a hole out with 6" BD on 20's. Any info would be good.
