You can't flip it, in any way. The flywheel gets un-even, hot spots and cracks. It has to be resurfaced to make new again. The new clutch disc will take shape to the old flywheel and cause the pressure plate is smooth all the un-even wear makes it chatter.
Just like doing a brake job, you can pad slap it but it's not right. Your asking for noise, and with a clutch your asking for chatter.
Alot of small shops don't resurface because they have to take the flywheel to a tranny shop to have it turned, it takes time and you might never have a problem.
