i think the egr valves are the same. i did have a efi version before this one. my egr valve mounts to the head after #4 then the tube runs to the intake maifold.... so i just went out there and looked at it... that smog pump pumps air into some round thing mounted to the inner fender well, and that has a hose going to some thing mounted to the block and sends air into the exhust manifold where the o2 goes.. so i think i just need the o2 block off plate, and i'll be set.
