you might have torqued the cams down and the piston might have been up and when the valves opened hit the top of the piston and snapped the cam. u might have bent the valve also

I would say they are quite easy to break if you don't fit them exactly right, they are only sand cast bits of steel...

I agree, i was chucking some old XE cam's out and decided to seee how strong they were. They all snapped very easily.
