340 Lifter failure, now what

Current developments.
Bought the Crower Cam Saver lifters.
Today I pulled intake.
7 retainer clip failures total.
4 bent pushrods (1 looked like a Z)
Cam isn't the most beautiful, but all old lifter were worn with a circular pattern so that means it was ok...
Not sure how the engine ran as well as it did right now... because it probably shouldn't have...
