lifters

hey guys rebuilding a 440 im planning on using the stock everything. just putting it back together on the cheap and getting it running. my question is if im using the same cam can i reuse the lifters?

i was told once that if they do not go back in the same cylinder that they came out of they might collapse. is this true? i got the engine taken apart already and the lifters were not labelled so i want to make sure first.

thanks
marc
