Re: Roller Rockers or Extractors
Im pretty sure everyone will agree that, the exhaust system will give you heaps more gain than the roller rockers!! But as I found i lost abit of lower down torque, it was rather un-nerving, but once the car was chipped the difference was huge.
The difference in power form the valve lift, to extractors will be quiet minor im sorry my friend.
