rodeeoo,
I believe we've already explained to you the difference before in prohatch forums... still trying to be in denial ar??
Reprofiled cams will never be able to match up the performance of proper aftermarket manufactured cams.
Like what I did mention in my reply... and mentioned again by V8_nutter, reprofiled cams get its lift from playing about the valve's seating, adding washers whut so ever just so that the valves can properly REACH the now regrinded cams... not exactly a very highly recommended thing to do. I'd rather spend a lil' more and get proper high cams with properly tuned uprated valve springs to go along with it.
xcheong,
matspeed/powerzone cams are around 1.8k liddat lerz... RPW if not mistaken around 3.2k liddat oni lerz... so let's say around 1-1.5k difference... if you wanna get high cams, chances are you're gonna need to spend a large sum anywayz... having to get adjustable pulleys, uprated valve springs and an engine management to fully utilize the high cam's potential... 1-1.5k diff might not seem like much.
