I agree you should lap the flywheel to the crankshaft to ensure a proper fit.   Also, I found out on a previous restoration job that a woodruff key from the hardware store may not be quite the exact fit, so better to order the correct key.    Finally, after lapping the flywheel/crankshaft tapers and installing a new key, be sure the flywheel and crank tapers are perfectly clean and dry and the flywheel nut is tightened to the correct torque of 40 to 45 ft. lbs.
