Solid cam damage diagnosis help

I've broken in cams with dual springs for years. Never had a failure. Not one. As long as you use the right break in lube and an oil high in zinc content and follow the correct break in procedure, you won't have a problem.
I am with you on your opinion, that is what I believe happened. engine start up was attempted at least 12 times with EFI, probably went another 2 weeks until the carb was installed and fired up. Being the situation i'm in I am considering just taking out the inner spring for break in either way. I would just hate to have to open it up once more.
