When you drain your exhaust manifolds via the quick disconnect you have to make sure that water flows from both lines.....the drain hose/fitting on the manifold can become plugged and the manifold may not drain completely. I placed a t on mine and clamping one hose I can drain one manifold at a time to make sure neither fitting is plugged.....just poke your block drain hole and you will see the debris that can plug holes
