If you study fluid dynamics, you'll find that the lion's share of the flow goes right down the center of the vessel and that silly stuff like gasket matching doesn't add that much to the mix. Matter of fact, if the port ends up looking like an anaconda that swallowed a pig in side view, the mixture will slow down there, possibly separating fuel from air and puddling fuel on the port floor, to be sucked up on the next intake stroke as a big slug of raw fuel. You can see the effect of flow by looking at a stream or river, where the majority of flow goes right down the middle of the river, with little or no movement on the banks. So it is with a manifold/head port, the mass of flow going right down the middle with little flow at the edges of the vessel.
Bottom Line......
Bolt the intake on and run it.
