I'm fitting a new cam kit to my head which has just been skimmed. relapping the valves etc and fitting all new gaskets. I've been told to run the cam at 2k rpm for 20 mins to bed it in. After that what do i do?I've heard loads of different things, get it checked, run it for 500 miles off boost retorque head then have it setup. what do you guys think is best??
