raptor 660 raptor parts

Hello all! Im new to raptors and have been slowly getting the parts together for it to run jetted, plan to do the clear tube method and was wondering if a high performance cdi is worth it? Or do you feel just the jetting will do the trick to full throttle response and less/zero bogging...

cams binding bought new cam need a new cylinder head and rocker new are way more than I can afford any help would be appreciated thanks
