Tony I'm just curious, but what oil do you use for cam break-in? Outer springs only? RPM during break-in?
I had a set of Comp EDM lifters years ago that had not been properly hardened after the EDM process wipe out a cam but never have seen this type of failure! That is UGLY!!

Brian...I coat the cam with the paste that come with the camshaft.....after I do the initial lash settings...and before I bolt the intake on...I go over the camshaft again with paste....I have been using Lucas 10w-30 Hot rod oil

The engines fire right up...and I set the timing right of way to 32 degrees.....rpm...varies 2000 to 2800........with EDM lifter....I should not be being worried about the cam getting oiled...LOL

I dont remove the inner spring...but i have been doing this for upteen years and never removed the inner spring...last summer I put a MP 590 in a 360 with the SM heads you did for me....broke in the same way...No problems....as I said before I removed a Hughes 5460 cam that went flat during break in....put an old MP571 oval track cam in it.....it is running just fine...and faster then the Hughes cam.....
