you have to call isky for the specs. Then have a local regrind shop regrind yours or set you got from the J-yard. A local place does regrinds at 80 bucks a pop. Cam gears can be spendy but if you cruise the z31 sites you can find them cheap. Honestly, its the only way you will see REAL power from an NA engine. peace.
