Magnum rocker arms..any problems??

Well it's a big debate whether they will outflow an LA. I like the velocity on the magnum as it helps with throttle response. But the ports are too small to be used on a serious 360 etc. A teen would repond really well. As siad the magnum will NEVER touch an LA's peak flow #'s.

However,add all the flow #'s together and divide to get an avg. you may be surprised at how much the mag really does flow.
