Another 416 Stroker Build-Pic Heavy

sorry if it seems off topic, but seeing the ports made me think. has anyone ever 'siamesed' the inlet ports in the intake manifold and head and if so did it help with the pushrod area restriction? or would it cause too much turbulence between cylinders so close to the valve?
the manifold would have 4 large runners not 8 and in the head just past the pushrod the ports would split again.
neil.
