That was my configuration. I had a Roush 427IR with the 8-stack. Your only consideration would be if you have emissions testing/inspection that may require it. But if you already have it why get rid of it? The breather will get some (although not much) oil in it.

"But if you already have it why get rid of it?" Purely for aesthetics. I am not required to have the PCV for state emissions and I find that a breather on the valve cover looks better than the PCV.
