OMG! Not good... I heard something about bad Piper Cams reliability...
Probably, OEM cams are the best choice... Maybe it's better to invest on valve springs and valves to increase power.
How about valve springs to increase power? Read a lot about dual vs beehive layout... What's better to increase rpm with OEM camshafts?
I heard also that OEM rocket arms are not so strong, and there are no aftermarket upgrade to increase reilability...
