well the magnet test seems valid enough for me, the magnet attracts to the springs, but not the retainer. Isnt there a tool that i can measure the springs with... if so, I can see if they are good enough for stage 2 or 3 cams. Also the stock cams were not used in a previous setup so i am guessing that the springs and retainers are not oem... I am still gonna take em out and spec em down and see if i cant measure the strength of them, because i am gonna get flat faced valves. Anyhow i appreciate the help
thanks,
Steven
