Step 1, slap a belt on it, and perform a leak down test. Will tell you how many damaged holes. Miracles do happen, you may escape undamaged.

Step 2a, Dead hole(s), pull the engine, pull heads.
(if only light impact marks on piston crowns, replace and re-lap only damaged valves and seals, check all valve clearances. Ship it.)

Step 2b, Heavy impact marks on pistons, highly likely piston is fractured or visibly cracked. Find a used or JDM long block, or sell it all as is.
