Edelbrock, TrickFlow rocker question

This lifter turned in the bore and just polluted a great fresh engine with trash. Of course it killed my 90.00 used Reed cam that i
Loved.
When I first pulled my intake I didn't catch the broken tie bars at first. When i was stuffing a towel into the lifter valley to catch debris from cleaning the intake area of the heads that's when I saw the first one, and I'm like "what the hell?" Then I checked the others and found the opposite cylinder broken as well. Lifter bodies were completely intact, just the tie bars had broken cleanly where they attached to the lifter body for the exhaust side of the cylinder. Still scratching my head over that. And like I said, made me wonder what broke first, the lifter tie bar or the rocker arm.
