remove EGR hump

what are you grinding down? normally you just take the egr off and put a Mr Gasket block off plate on with 2 bolts in the stock locations.
 
Near the rear of the bottem section of the intake on the 82 and 84 crossfire is a egr hump. You grind it down to allow for better fuel distribution in theory anyway.
 
You can use a block off plate were the egr use to be and do nothing to the interior/ some weld it up.

Or you can remove the whole thing inside and remove the outside pod and weld it up, I like this one;
