Vortec head conversion - EGR

I am going to be swapping some vortec heads onto my 76 C10 pickup in the next few months and I want to keep my EGR. I know there will be those who say just ditch the egr but I am wanting to eventually update most everything on the truck and pass emissions. We do not have a visual test, just the gas analyzer test. My question is this, how is the exhaust gas plumbed to the intake. I am aware that I will have to weld a pipe into my #5 or #7 header pipe. However, does that pipe run to the top or the bottom of the intake and if it is to the bottom of the intake, how does that work? Does there have to be a hole drilled through the heads or the block to run the pipe through? Any insight would be greatly appreciated. I have been searching on this for a few days but am coming up empty handed. By the way, the truck has been converted from carb to TBI so the intake I will get will have a place for an EGR.
