so I'm about to put together the pieces and I have a couple quick ?'s... My intake and gasket are not going to deal with the port under the double port in the center??? What is that lower port? Can I leave it exposed to the world?? When I look at my Haynes their gasket doesn't seem to worry about it but I know my factory one did...Looks like RB set up would cover it....do I need a plate to block it off????

If I am not using the cooling ports for my intake do I need o-rings on those ports?? Seems to me I read somewhere I don't need the o-rings anymore.

Thanks

20mm freeze plugs will do the trick for the coolant ports, saves a lot of having to dump the anti-freeze everytime you take off your manifold. about the other port, i'd say don't worry about it, but i don't know how it would affect it, seems like its not really needed.
