If you have a Hayes manual check out some of the Canadian emissions systems from the early to mid eighties. I don't have the manual near but I did this on a 86 2wd 22r with a 32/36 and it passed emmissions in AZ (roller test) with flying colors. You pretty much figure out which vac lines are above the thottle plate and which are below. Then hook them up accordingly.

On my 86 22r with a 38mm I blocked the entire system without any major ill effects. I've had to do alot of engine work with it but with all the perfomance stuff on it and how hard it's run it's difficult to pin problems on minor things like the EGR.
