I was doing some more checking today on why I did not have compression on the #8 cylinder. I was watching the rockers as I turned the motor over. Something was not right. I pulled the rocker off and I found a broken valve spring?

I called summit and they are sending me a new one. I'm running somewhere around .538 lift. The spring is rated at .560 is this to close? I have heard of broken springs ,but have never known anyone that broke one. I don't think I'm runnnig any crazy lift.

Just wanted to let you guys know I found the problem. Thanks for the help everyone.
