Has anyone experienced a failed stock aluminum rocker with new higher lift cam and 918 springs?

i wouldnt worry about the rocker failing as much as the springs or the rocker backing out.

What is the lift on your cam? You can use Harland Sharps, Crane, or Jesels as a replacement. Im don't think there is anything to worry about. The stock rockers are lighter on the nose, helping to prevent valve float. There are alot of people using them without a problem, I spent the money and really didn't need to.

I did a little more research and discovered that the stock rockers are investment cast steel. Phew all that worry for nothing!

Here's the link to the manufacturer for whatever it's worth

I have it sucks. Bearings were every where. I have a MTI C2 came and the MTI stage 2 heads. So whatever springs they use. They only had 3,000 miles on them too. I now have Harland Sharps.
