cold feet about potential bad lifters

MopaR&D said

Man that's a huge bummer. I have some other questions if you don't mind... did you happen to check the lifter faces for being convex (slightly curved out) before you installed them? What about rotation, did all the lifters spin freely and smoothly in their bores? And I'm not sure if it's possible to determine but can you tell if it was a cam lobe that failed first or the lifter?.

I didn't check them for being convex but I did run every lifter into it's respective bore and they all moved nicely in my opinion. My opinion might be wrong but I'm fairly confident that the lifter bores were in good shape.
In terms of problems with the break in, motor wasn't primed, and I was using the new aftermarket valve springs.

Is there anything that I should look for when pulling the engine apart in terms of finding the failure mode?
