You can eliminate pretty much all of that stuff. You will need an egr block-off plate, which you can make yourself or buy one. Another thing that is an issue is the thermactor pipe that connects to the rear of each head and into the exhaust. They make plugs for the back of the heads. Alternatively, you can cut off the fittings, turn them around, and bolt them back on with a little high-temp rtv. At the exhaust, you can saw it off and weld up the hole. A strategically placed band clamp or two might be a good temporary fix. You'll also need to cap off any unneeded vacuum nipples. You should have a vacuum tree on the firewall that tells you where each one goes.
