DOHC Engine fitting - Manifolds

[Enoch]

Hi folks, just trial fitted my engine to see what sort of clearance issues I might have. I have worked out that with about 3 1/2 inches of ground clearance for the sump the engine should just about fit with a standard height scuttle. The inlet manifold is a pain though as on the i4 engine it sticks up way above the rest of the engine and would need a huge bulge. I am looking in to whether a manifold from an 8 valve Galaxy would do the trick. Looking in the Haynes manual for the galaxy it looks like they used the i4 engine at some time but it did not have that huge lump sticking up. Anybody know if this is the case or not? If so then going hunting for the correct manifold seems like a fine idea.
Thanks in advance,
Enoch.
