if you live in the US the silvertop will not pass smog. end.
most of the vac lines are for emissions, so you dont really have to worry about them (if your going to fail, why make you engine even try, get rid of all that junk)
there is only ONE vac line in my swap that i drive daily and that is from the vacuum port by cylinder 4's throttle body going to my brake booster. there are a couple balancing lines on the bottom of the ITBs but those ehould be untouched and if they where its slf explanitory how to hook them up. there is also the PCV but it is cramed behind the injector loom and should be hooked up ok. you should also plug the front vac line (my back vac line was plugged so i just moved the cap) if you dont know what im talking about, stop and find someone who does to help you through the whole process.
good luck with the swap, mine has some bugs but it is awsome to have a silver top in a 86.
