I have a 5.9 that leaks coolant from the corners. This engine hasn't run yet. It has new EngineQuest heads( not the NZ ones). I have tried 2 intakes and 4 sets of gaskets with the same result. If the heads had been resurfaced could that affect the sealing surface to the intake manifold? This is my 3rd 5.9 I have put together and never had any sealing problems.
