Throw away those small intake gaskets that run between the heads and use hi-temp silicone, place the intake gaskets on the heads and set the intake on the engine very gently, look on both ends and this will give you an idea of the bead you need to run, lay the bead on a little thicker than the measurement, let it set over night, put the intake back on and torque it down. Also, I use a small amount (on my finger) to go around the water crossover. After installation you can use a razor blade to trim the excess silicone, very clean look and never a leak.
