flywheel HELP!!!

Do i have to resurface my flywheel after installing a clutch, the clutch im installing is a used stock one so has anyone gone without resurfacing their flywheel??? or is it a must???thanks

i know its not a MUST, but highly recommend it... my old flywheel was GONE, luckily i bought the billet steel flywheel to replace it, my friend on his stang 95 gt, just cleaned it off, and put new clutch on it... not a must, but if can, do it

thanks i'll probably go with out it since my clutch is used and im planning on putting a cam in this summer then putting a stage 2 in, all i need is this to get me from point a to b or cruise but thanks alot for the advice.
