350 MCX, water leaking around intake manifold

Anyone had problems with water leaks around the intake manifold before (and fixed it)?!

After installing our new engine we've got a water leak, seemingly coming from the top of the intake manifold (right above the cylinder intake on #2 cylinder, by the rocker cover). We've had the intake of twice now to check the gasket was seated correctly but it still leaks (only when running).

One thought, we're using a reusable intake gasket (which seems quite thick). Anyone else use these, or do you guys stick with paper gaskets?

Any ideas? Keen to sort this out.
