Got the lifters back from Oregon cam grinders, they look excellent, disassembled each lifter and cleaned internally, and in case yall thought we were sleeping, started the shortblock assembly.

Question, My old purple cam was put in the box my new cam came in.
I read on the box , warranty void if use of reground lifters.
Your thoughts on why?
Thanks
