I live in NC. Me and and some guys at work are using a 1990 Integra to compete in the Chumpcar series. This looks like a pretty informative site.

The car has a cage in it, most excess sheet metal removed, everything except the alternator removed from motor, and the brakes/spindles upgraded. We now are looking at installing a header. We found one on craigslist close by that was listed as fitting a b16.

With little help from google and this site, it looks like exhaust interfaces on all b series heads are the same.

Great site. Thanks.
