Ugh, now what?

If I were going into it that far, I'd be real tempted to just replace the flywheel, clutch and pressure plate while I was there, unless I knew for sure it was like-new.

It's all going to be out of the car for ring gear replacement anyway, and a good quality new steel flywheel and clutch assy for a SBC will run you < $600-700. Maybe worth it to save yourself from doing the job twice if parts look like they are going to need replacement in a few years.
