Had the same thing, chased all of the normal things and ended up being the intake gasket. Replaced it with the correct gasket. Roush and other MFG's were using the wrong gaskets in the beginning. Leaking from the bottom side of the manifold 2 cylinders affected. Pull carb and stick a mirror down the runners, shine light down runner and see if any are discolored in area of gasket, mine was dark around cylinders affected. Good luck!
