If you threw a rod I would be looking for a replacement engine. The rod more than likely cracked or broke the block. The piston can contact and bend the valves. best thing to do is tear it down and determine the extent of damage and have a machine shop look the parts over before ordering parts. If you are on a budget the used engine is the least expensive.
