i have a 90 integra with a decent non-vtec b20b i recently saw that people r swaping cams n their b20 with the b18 cams because of b18 topend power but from what i can tell the only gain as far as lift is concerned is the b18intake cam paired with the exaust cam of b20! seems like the way to go! basically the b20 has a bigger exaust cam than the b18{has this been done}
