im sure they will fit the only thing that you will have a problem with is the egr bung on the passenger side header. other than that fitment shouldnt be a issue.
yes, they fit.. I have the 86-93 bbk unequals on mine.. you will have to buy a cap for the egr tube, which is cheap. either that or cap off the vaccum line with a screw and the check engine light will stay on.. doesn't hurt though
unless you have a tuning device and can disable the EGR function you should keep it hooked up.
With it plugged and still enabled, the EEC adds extra timing when it "opens" the valve and without getting the extra exhaust gases/air you will get more detonation
EGR cools the cylinder temperature preventing pinging or detonation which can really screw up your engine. It also increases fuel economy and lowers emissions with no detrimental effects on performance as EGR does not operate at idle or at WOT. So there are no real performance benefits of deleting it. I capped mine off earlier because my LT headers didn't have the EGR bung and my car pinged like crazy. I did the Fox TB conversion and now run a Fox EGR setup (no SN EGR plumbing!) and my pinging issue is solved. I also get better gas mileage with the EGR reconnected.

oh.. hmmph, only time my car pings is if I put 87 octane in it. I run 89 and 93 all the time and never get any pinging.. as far as gas mileage, Im not technically worried about it because I only use about $50 a month for gas.. I love living one mile from work
