Okay i am kinda lost to, I wanna get the comp cams nsr and I called American muscle and they said I still needed to put the phasers on even with these cams and I need to know who has put on the cams with out the phasers cause I know there is a big chance the valve can hit the piston so if you don't think I need the phasers please let me know we're you got your information from and weather I need them or not
