Just be careful that the machine shop does not set it up using the carb flange as a right angle position index point. I had a great manifold on my 8N done by the machine shop and they faced it 90° from the carb flange and when I tried to install it the carb fell too close to the block. The face of the engine block is about a 2° from perpendicular, so beware.
I had a thin plate made up to insert between the manifold and the block that was cut with a 2° bevel to correct the angle, that and two manifold gaskets fixed the problem.
