There is one other thing to note..... your engine is 1800cc. Have you fitted twin carbs to this engine to replace a single carb? The single carb manifold has a water bypass feed , where water passes up, to warm up the manifold. Under the inlet manifold, where it bolts to the head. on the "front" gasket, near the themostat housing, there is a water feed hole where water goes up into the manifold. The hole is the same size as a small core plug. When fitting a twin carb manifold to 1800 head, this hole should be sealed up with a core plug, as the water feed is not required on the twin carb manifold. If this is not done, the front manifold gasket is the only thing that's sealing the area, and water can be forced past the gasket, into the inlet / fuel side, filling the cylinder bore with water. In case of an extreme leak here because not sealed, the water will pour out of the engine here, like a burst water hose. (pisses out)
