The Purpose Of 1.6 Rockers

i HAD a MP.508 but like moper said" I DONT NEED THEM TO GRIND A CAM TO DUST!!!...AND LIFTER TOO!!!".....im running STOCK/OLD rockers on my NEW comp XE294H CAM which is .519/.524....im sure the lift is no where near that with my old/stock rockers and ive run a 12.07@108 in street trim already!!!!!,THANKS to MOPER!!!! :headbang:

now,im hopeing to run BETTER/FASTER with the NEW pro-magnum lifters and 1.6 rockers....i think moper is right,its about the valves opening/closing.
