I bought a DOHC ZC a couple of weeks ago and it is almost in. I was wondering about cams for it. I have never bought any aftermarket cams for any of my cars before, and was wondering if I buy new cams for my ZC, what kind performance, good or bad, would it create. What are some good brands? Are they even worth getting? And if I do decide to buy them, where can I get them for a ZC motor? Thanks.
