I was tearing down the 93 head I'm going to eventually use on my 91 GS and saw the EGR valve on the 93 intake manifold. Is there a passage ported through the head that I will have to be concerned with for the swap?

Right now it seems like the easiest thing to do would be to use my 91 intake manifold on the 93 head. I'm assuming the 91 intake will cover the hole for the EGR on the 93 head. Has anyone run into this?

We are also considering leaving the 93 intake manifold on the head and putting a plate where the EGR is. Will the 91 fuel rail and injectors work with this option?
