The six bolt holes for the crank are not equidistantly spaced, so you’ll quickly find that the flywheel will only fit on the crank in one position.
If you have heat cracks in the surface of the flywheel (and machining doesn’t remove them) then throw it out. If the flywheel explodes it can cut your feet off. Replacement flywheels, even SFI approved ones, cost less than $300. Make sure your new flywheel has the appropriate balance weight: either 28 oz-in for 260/289/302 engines, or 50 oz-in for 5.0 engines.
