I'm not sure if it was mentioned yet in this string, but the factory index mark on the crank sprocket doesn't indicate TDC but rather it places the crank in a "safe" zone where none of the pistons are at the top of their stroke. This allows the cams to be rotated without causing any valve/piston contact. When manipulating the crank and/or cams it's best to have the spark plugs removed to eliminate any compression resistance. That way it's easier to detect any valve/piston contact that may occur.
