360 Re-Ring? Temporary Engine. Will it run fer a year?

I've done quite a few rerings with a rigid hone followed by the ball hone. The key is how much ridge you have. The rigid hone will tell you the definitively after a few revolutions. I like to hone the crap out of them with the rigid hone. The extra clearance will make them good rev'rs. Crosshatch the walls. Be sure to remove the oil galley plugs. A shotgun cleaning brush wotks wonders at getting the crud out of the oiling system.
