Sage advice from NewZed. I will add, regarding cams, that it's best to get a re-round cam not new. There is a guy named Bonk on the Fakebook forum "Church of the L". He sells custom re-ground cams and appears to have lots of happy customers on the forum. If you do use him he can give you some advice on setting up/running in the cam properly - as it's easy to do it wrong and trash the cam. Otherwise there is a lot of information on this forum on how to do it properly, you just have to dig a bit to find it (I use a Google search - "search term site:hybridz.org" When it comes to rockers, you want NOS or OEM/NISSAN, not regrinds. I have had reground rockers trash themselves and the cam. I installed new Nissan rockers and haven't had any issues since.
