Two questions for the tribe:
1) Is anyone familiar with GM clutch/flywheel/spring plate stackup and want to comment on the worn off flywheel bolt heads from the clutch plate spring tabs? What caused this? (pics 1&2 the shiny bolt heads are like that on all 8 bolts. Pic 3 the shiny part just inboard of the springs is what rubbed the bolt heads.)

2) If I re-surface my flywheel it's $65. If I buy a new flywheel from Rockauto it's about $65 with freight. So I want to buy a new one. But I seem to remember something about how on the V6's maybe a new flywheel needs to be match-drilled/balanced to mimic the old one? (Or am I confusing issues with swapping a V6 motor from auto to manual trans?)
