360 rebuild advice

My question is since i'm re-using my lifters and pushrods (assuming they're still in good shape) do they need to be numbered and matched up the same when i put it back together or does it matter? thanks guys

I'm going the otherway and guessing you all ready have the whiplash cam and lifter set up.

Each lifter should go back onto the same spot in which in came from. This way the lifter is matched to the cam lobe.
