Basically I had somebody put in a new headgasket for me, and he didn't put the key that holds the cam gear and intake cam together back all the way in, so it totally screwed up the end of my Integra Type R cams. The guy did give me a set of b16 cams from a '99 Si to put in until I got another Type R intake cam. The machine shop that did some of the work said they couldn't machine the end of my (otherwise perfectly good) cam, so now its just a big expensive paperweight.
