Ford gave a spec of .005" maximum run-out on the flywheel. As a side note, the max allowable runout for the RING GEAR was .010". The shop manual states that after checking the flywheel runout, if it exceeds .005" be sure to remove it and remount the flywheel by 180 degrees....and check run out again. If the measurement is still above .005" the manual says to remove the flywheel and check the run out of the mounting flange. In other words, the problem could be the crankshaft mounting flange. Would be a bummer to replace the flywheel and still have a problem. Take the measurements out close to the edge (but not the actual ring gear).

The flywheel-to-crank flange bolts get torqued to 75-85 lbs. The pressure plate-to-flywheel bolts get 17-20 lbs. The manual states to align the flywheel onto the dowel pins, install and torque the bolts. It can take some wiggling and tapping with a rubber mallet to get it started. Make sure there are no burrs or other damage to the dowel pins, or the pin holes in the flywheel.
