I'm going to stick some 80k mile E7's on a cammed 302, they came off a running motor that didn't smoke or make any noise. I dont have any intentions of pulling these after I put them on for a long time so besides valve seals what else is worth changing, springs?

Tough to say but expect some valve float. New springs would be recommended but then you're investing $$ into junk heads. You could always try them as is and add parts later. If it didn't smoke I wouldn't bother tearing em down. If you MUST tear them down, seals, springs and a quick valve lapping and call it done.
