It will be tight BUT if you've eliminated the EGR...there may be help. I did this on my edelbrock elbow....I assume you run the elbow correct? The bottom bolt that holds the EGR/EGR block off plate threads into that long "horn." I cut that off and ground it down smooth and made a block off plate out of thick steel. Made my own gasket, cover it in black silicon, and slapped it on. YES, only one bolt was holding the plate down BUT it holds it PLENTY tight to prevent vaccum leaks. In a boosted application, I'd do it again BUT, I'd fill the elbow's egr port with epoxy (jb weld) and smooth it out on the inside...and put the plate on there. Anyways, by smoothing out that bottom "knub" or "boss," you may be able to clear the valve covers without a spacer. That intake is BIG...but I think with only a 3/8th spacer, you should be good.
